I actually have two wildly offset storylines that evolve both the Canon and the EU:
Also these are unfinished but if you wanna hear your thoughts or criticisms, please let me know.
The Mandalorian King:
In this AU, Obi-Wan Kenobi is found by Darth Sidious instead of Darth Maul and is trained in the Dark Side but abandons his master to find his old love Duchess Satine Kryze of Mandalore and become the King of the Mandalorians and an enemy of the Old Republic and the Jedi.
Darth Plagueis would be confronted with a vision of Obi-Wan (Ben) Kenobi fighting Darth Vader, and to prevent his visions of the future from coming true, he uses a Force Hallucination secretly on both Yoda and Darth Sidious to switch up apprentices; Sidious, disguises himself as a kind and innocent farmer goes to Stewjon and meets the Kenobi’s’; there he befriends them and tricks them into taking their toddler son, Obi-Wan Kenobi and buy him from them so he can teach him under his ways of farming (The Force;) at the same time, Yoda and Qui-Gon Jinn goes to Dathomir to meet the Nightsisters and Mother Talzin to befriend them as well and agree to take Talzin’s zabrak son, Maul Opress under Qui-Gon’s wing
Over the course of the next 21 years, Maul would be trained as a Jedi and be given a Green double-bladed lightsaber and Obi-Wan would be trained as a Sith; over that time, Sidious began scheming with the Trade Federation much earlier than in the regular timeline and he and Obi-Wan started attacking planets like Mandalore but that failed once Obi-Wan ran into and fell in love with Duchess Satine Kryze and after seeing the might of Mandalore, they were forced to retreat and take on another planet, Naboo
Qui-Gon and Maul would go to Naboo like Obi-Wan and Qui-Gon would in the regular timeline and rescue Queen Amidala and go to Tatooine and free Anakin Skywalker from slavery and leave his mother behind, but would still be attacked by Obi-Wan; the difference here would be is that Obi-Wan is still attached to his love for Satine and yearns to be back with her; then on the night he is ordered to go back to Naboo and kill Qui-Gon and Maul, he vanishes and goes to Mandalore and reunites with Satine; Plagieus is still killed out of Sidious’s rage of Obi-Wan vanishing and Naboo is saved but Anakin is made Qui-Gon’s new apprentice while Maul goes on to face the Jedi Trials
Three years after the battle of Naboo, Satine and Obi-Wan marry on one of Mandalore’s moons and he renames himself Janusex and they become the Mandalorian King and Queen
Count Dooku around this time becomes Sidious’s new apprentice and is far more powerful and unstable than in the actual timeline
Anakin and Maul become Jedi rivals in this timeline because of Maul becoming one of the Jedi Council and Anakin yearning to become more powerful than him against Qui-Gon’s fatherly relationship with him
Maul, Anakin and Padme Amidala have a love triangle in this AU and like in the real AU, Padme is friends with Satine but knows nothing of their cruel Mandalorian King, Janusex (Obi-Wan)
Palpatine eyes both Anakin and Maul to be one of his apprentices
Anakin returns to Tatooine and tries to rescue his mother but fails and slaughters the Sandpeople like in the main timeline
Jango Fett is raised on Concord Dawn in this universe and raised into the Mandalorian Army and assigned by Janusex and Dooku to assinate Padme to bring Maul, Anakin and Padme together on Naboo and Dooku and Qui-Gon to meet again with Janusex
Qui-Gon is taken by Dooku and escapes leaving Anakin and Maul to work together to fight Janusex who beats them and cuts off Anakin’s right arm
Anakin marries Padme in secret as in main timeline
Instead of a Clone Army, the Republic enlists regular men as soldiers to save time and resources
Janusex and the Mandalorians play a much bigger role in the Clone Wars than they do in the main timeline thanks to Dooku and Grievous and are in charge of wiping out the Nightsisters, than the Battle Droid army
Palpatine is captured and Anakin overpowers and kills Dooku as in the main timeline
Palpatine reveals he is Sidious and after Anakin gives into the Dark Side and allows him to kill Mace Windu, Anakin becomes Palpatine’s apprentice, Darth Vader
Maul goes to Utapau and kills Grievous and Order 66 issued while there and he flees into the galaxy
Janusex and the Mandalorians are discovered by Palpatine and Mandalore is attacked by the Empire, Palpatine arrives and Janusex duels him and Palpatine threatens him with Satine and kills her, Janusex flees, he goes to find help with any surviving Mandalorians but they’re all gone; but he goes to where he seeks refuge as all runaway Mandalorians can go to, Coruscant; there he finds the Jedi Temple, he finds Qui-Gon, Maul and Yoda regrouping while hiding in the shadows and what they plan to do to stop the Sith; he wonders if he should join in to avenge his people but he is then attracted to a room of Holocrons and takes the center one that attracts him the most
Janusex learns that Qui-Gon and Padme are going to Mustafar and he sneaks aboard the ship unknown to them while Maul and Yoda face Sidious; both fail, Yoda and Maul go into exile on unknown planets, Qui-Gon is killed by Anakin and leaves Padme on Mustafar after feeling betrayed by the fact she sided with Qui-Gon; but Janusex resuces her and takes her to the nearest space sport and hospital, Polis Massa where she gives birth to Luke and Leia and he promises to raise them under his care and she dies afterwards; he leaves with the children and tells the Polis Massans to take her body back to Naboo to be buried
After 19 years of training, private adventures of finding Jedi artifacts and writing in a Journal, Janusex is learning to become a Jedi along with Luke and Leia and when he saves a mandalorian (Pre Vizsla) from the Empire, they’re forced to go on the run; even though they don’t see eye to eye, Janusex thinks this may be the best chance to rebuild his Mandalorian regime and the Jedi but they’ll need help; he tries some meditating and actually contacts Qui-Gon’s spirit who tells him to go to find Maul on Dathomir
This is where the Mandalorian King ends on story ideas. And now for my second AU:
The Resurgence of Skywalker:
In this AU, Anakin Skywalker/Darth Vader survives the Battle of Endor and lives past “Return of the Jedi” and onto into the events of the sequel trilogy and finds a path to finding a way to redeeming himself to the entire galaxy for his crimes with the Empire and as a Sith Lord
Vader is restored back as Anakin and kills Emperor Palpatine/Darth Sidious on the Death Star II and restores balance in the Force (for the time being) and he and Luke share a moment before Anakin loses consensus; but Obi-Wan Kenobi’s ghost would appear and touch his forehead and his own reviving him and giving him the strength and energy to live once more; Obi-Wan tells Luke that Anakin’s work is still not done and that he must stay alive and that once he gives most of his energy up to Anakin, his time in the Netherworld will begin to expire; before more can be explained they flee off the exploding Death Star
Luke regroups with Lando, Han, Leia and Chewie and they’re horrified that he is with a wounded Anakin/Vader and he tearful pleas for his father to be given medical treatment and removed from his torturous suit; they agree but they arrest him and take him to Chandrila, where Mon Mothma and Rebel Leaders are planning the early stages of the New Republic
Anakin/Vader’s trial would be from his medical bed as Medical Droids fix him a new suit under Luke’s direction; galactic publicity would try to make Anakin/Vader answer questions that he would stay silent until he was alone with Luke and his only response was “Padme;” this would go on for days on end until Leia convinces Luke to use some sort of Force Trick on Anakin/Vader to probe his mind
Luke unfortunately does (like Kylo Ren does with Rey in “The Force Awakens” in the main timeline) but when he probes his father, he sees a vision of his father Force Choking a woman on a volcanic planet and a Japor snippet which angers Anakin/Vader and the medical room around him, Luke, Leia, Han, Chewie, Rebels and the galactic publicity reporters begins to rumble and the medical droids begin to crumble and explode and the Rebels, Han and Chewie begin to point their weapons at Anakin/Vader and he uses his mind to implode them, he uses the Force to free himself and attacks them all
Anakin/Vader flees into the building, engulfed in his Force Rage but is stopped in a room by Luke but when Luke tries to touch his head, he burns himself, but Obi-Wan and Yoda’s Force Ghosts cool him down and they tell Luke that if Anakin/Vader is to survive and to truly redeem himself, disappear, both of them; Luke sneaks Anakin/Vader out through a Rebel Shuttle
The Rebels discover Vader escaped and Mon Mothma orders an immediate search throughout the whole galaxy, Leia tries to telepathically contact Luke and he says to her that he and their father have a job to do and so does she because she is pregnant with her son, Ben Solo
Luke and Anakin/Vader hide on the isolated world of Ahch-To where they find The First Jedi Temple and they and Obi-Wan and Yoda use the force to use a Force Shield to avoid detection from any lifeforms
Over the next thirty years, Anakin/Vader and Luke begin training themselves with the Scarred Jedi Texts and the ways of the Grey Jedi, and the whole Galaxy and the New Republic knows by know they’re criminals and Luke is Vader’s son; Leia in this timeline is safe from the public knowing she’s related to Vader; Ben Solo has become a Senator for Chandrila and Han Solo is a general for the New Republic Army with Chewbacca at his side
The Empire has reformed into the First Order at this time and is at war with the New Republic; the Resistance does NOT exist in this timeline
Ben Solo hates being a Senator and wishes to be more like his father and to find his criminal Uncle, Luke Skywalker
Anakin/Vader has his own personal medication hub in a cavern similar to his Meditation Chamber
This is where The Resurgence of Skywalker ends on story ideas…
