I had a weird idea and I’m not sure there’s enough footage to pull it off. Since Kylo Ren/Ben Solo is easily the most interesting character of the sequels, and his parts are generally the highest quality, would it be possible to make one movie just from his perspective? I’m imagining it somewhat like A Christmas Carol, with Ben as Scrooge and Han, Luke, and Leia (and Chewie to some extent) following like ghosts and “haunting” him for his evil deeds. Some of this is already explicit in TROS and when Luke says “I’ll always be with you just like your father” in TLJ.
Since the focus would be on Ben, Rey would be the pseudo-antagonist, a star pupil trained by the OT cast to replace him, which builds his resentment until he grows to have some affection for her and Palpatine gets involved.
Obviously deleted scenes like the Oracle would help flesh this out a lot more.
This could really work well. Kylo struggles a lot in the trilogy so it could easily be re-edited from his perspective.
