The biggest issue with a 1 in 9 edit is the scale. We will quickly get overwhelmed by all the stuff going on without a main character. Setting it around the Skywalker Family just won’t work in my opinion, because every hour you’d be swapping out main characters.
My solution to the 1 in 6 fanedit was relatively simple- set it around Vader. The introduction of the ST complicates this manner. We could frame it as “Vader’s legacy” but unless Anakin suddenly arrives and saves the day in Episode 9 it will feel terribly anticlimactic because Vader’s story ends in 6.
Therefore I agree that Luke should be the main character. A non-linear storyline is the best approach. We’d start with the Empire- not First Order, the old empire is still in power- burning of the Jakku Village, which immediately establishes the overarching plot: find the legendary Luke Skywalker to save the galaxy.
Warning this got out of hand
This segues perfectly into a title card to Luke’s birth. Immediately after his birth (and mother’s death), we’d cut to A New Hope for Ben’s talk with Luke. It is implied Obi-Wan raised Luke. Then Obi-Wan’s old droids reveal the message from the princess and off we go- A New Hope up to the Death Star escape.
Then to TFA where resistance spy Finn finds Rey and BB8. They escape to Han, who tells them “it’s true, all of it”.
Then cut back to Luke on Hoth. He gets attacked by the Wampa and receives the vision for Dagobagh. Luke leaves the rebels before the Battle of Hoth, which makes him feels selfish. When he learns they’ve been captured after a defeat at Hoth, he blames himself and goes to Cloud City to rescue them.
The Vader reveal further complicates the plot. We get a 1-minute supercut of the Prequel Trilogy.
Meanwhile in the Sequel Trilogy, the Falcon lands on Takodona and Rey gets the lightsaber. She runs away and is captured by Kylo. We quickly establish Starkiller Base… “the latest death star” (in this edit, death stars never stopped getting built, like nuclear warheads).
Luke surrenders himself to Vader, and we have the finale of ROTJ from purely their perspective. The catch is the Emperor somehow survives, which explains why the Empire has survived up to this point. Snoke = Palpatine.
The resistance mounts an attack but fail. Starkiller blows up D’Qar, with only Leia and a few ships remaining. Kylo reveals he is Ben and kills Han. Rey takes up the lightsaber and fends off against Ren.
At the resistance ship, the rebels complete the map and Rey flies out to find Luke. The first half (more like first 2/3 rds) ends with TFA’s cliffhanger.
INTERMISSION
Now in TLJ land, Luke refuses the lightsaber. Very condensed TLJ- mainly concerns Rey and Luke with some cuts to the resistance being chased.
To prove his point that the Jedi suck, Luke flash backs to the Prequel Trilogy once again. This time we get a reasonable amount of time dedicated to the flaws of the Jedi during their “prime” and we begin to see his point of view. We also better understand his reasoning for attacking Kylo.
Rey leaves and Kylo reveals Palpatine has indeed survived the events of ROTJ. We either use ROTJ footage or TLJ footage to show Kylo eliminating the emperor and crowning himself the new ruler.
The conclusion of the film is on Crait, where the rebel alliance is to make a final stand. This has to be a defining moment for a bloated movie- so the R2D2 nostalgia scene is moved here to right after Luke’s lesson with Yoda. Then Luke outsmarts Kylo, and does little speech overlaid by the Canto Bight kid. Knowing his mission will be completed by Rey and the future generations, he becomes one with the force.
Whew this is tough
