I’d have Leia die in the bridge explosion and remove her from the rest of the film. I’d remove Yoda. I’d have Luke burn the tree. Sensing Leia’s death would prompt Luke to confront Ren.
I like the idea, but that way you’d lose the beautiful shot of the Crait big ass door closing behind her, or her scene with Luke. And have 2 older characters killed in the same movie could be a bit overkill, but oh well.
