I was worried about the same thing, but after seeing some test clips from a few people, I actually think it is doable. Once people start sharing more of what they’ve worked on, I think we’ll actually be surprised by how easy it is to make the movie work without it.
I guess we’ll see though!
I removed Rey Palpatine in my Workprint. And her arc still works. She’s battling her pull to the dark side, and she doesn’t have to be a Palpatine for that. She learns the worst news that her parents sold her to Palpatine to be killed. And also that she killed her own parents by crashing their ship.
