I was thinking of a radical change to all 3 movies.
Maybe there is a way to use Chewbacca’s death actually real as part of the larger narrative.
If Rey actually felt consequences and had to fight that demon in her mind…that’d make for a stronger character arc.
This would require something like her exiling to Luke’s Island being the actual end of a movie. In ROS, she went there and then left in like an hour. But if she actually did that at the end of Movie 2…that’d make her return in movie 3 that much more meaningful.
This would require heavy restructuring but I think it’s possible. Luke would have to be reworked as well–perhaps he is already a force ghost in TFA.
