It'd be a long shot, but I'd like to see an edit that switches the order of The Rise of Skywalker and The Last Jedi around. Perhaps the objects the heroes are trying to find are further pieces of the map to Skywalker, and the Last Jedi can serve as the ambiguous finale for the universe. I also feel like switching the order would help Rey and Kylo develop more of a rivalry, and make the characters reaching out to each other a bit more plausible.
Another one that'd be nice to see would be an edit of Falcon and the Winter Soldier where the final battle is Sam Cap beating John Walker rather than the Flag Smashers, but that'd be a difficult task for anyone.
