Having Palpatine have no plan for Rey would be nice because it would show him falling into the same trap the Jedi are guilty of, letting their arrogance and belief in their own power prevent them from seeing what is on the horizon.

Leia dying on Naboo is a great idea, as it allows her to end where her mother started. Make this movie rhyme with the others as much as possible. It is the last after all.

And any version that is meant to include Padme surviving RotS and dying while Leia is a young child, should absolutely consider giving Leia the pendent.

Ben in exile is a great idea, and one that could probably be executed, but without dialogue between him and Rey where he says something like "I’m staying here. It is my penance.’ It could be quite a head scratcher.
