Maybe I’m alone in this, but I think that since it’s already established in canon that Rey is a Palpatine, we should just keep that, improve it but not deny it, even if we don’t like that narrative decision. Changing something like that it’s too big.
Then why bother making a fan edit if you’re locking yourself out of ideas because it’s “established in canon?” This is a bad reason for not trying something unless you’re explicitly making a “canon edit.”
