If Maul and Grievous are one in this version like JXeditor’s Prequel Trilogy, then who’s going to fill in Maul’s role in the Siege of Mandalore? Ventress, Savage Opress, Cad Bane, or some other enemy?
I don’t think the Clone Wars show would exist in this theoretical continuity.
Having read through these nine-year-old ideas… they’re amazing! The only concern I’d have is a lack of screentime, as cutting all of Tatooine would really mess with the movie’s pacing. One idea I have is to start with an extended prologue of Obi-Wan (deepfaked Qui-Gon) finding young Anakin on Tatooine, ending with Maul’s return before a time jump of 8 years later. The only issue is you’d need to find a reason for Jar Jar and Padme being there. Maybe just deepfake them too, cause why not!
