I think if we are trying to find the most agreeable version of Rey Nobody for Ascendant, making Rey a clone of Palpatine doesn’t make sense. To me, Clone Rey should replace the standard Rey Palpatine, not be the version of Rey Nobody. Because Clone Rey still defeats the idea and theme of Rey Nobody. Imo, in a Rey Nobody edit, Rey should have zero previous connection to Palpatine or anyone else.
But I think something like Rey Clone or Rey Anti-Chosen One (Sith’ari) could replace a straight up “You’re Palpatine biological granddaughter”. Because you end up with the same point (the Skywalkers vs Palpatines if you’re into that) but avoid the whole idea of “Palpatine Fucks”.
Maybe I’m playing the role of pessimist but I feel like if I heard this Rey Clone dialogue in theaters, I would’ve rolled my eyes at it just as much as I did with the theatrical Rey Palpatine reveal. Sure, it’s different, but it still betrays the point of the the Rey Nobody reveal in TLJ.
Again, I guess this is just me voicing my point of view, but I believe the most inoffensive version of Rey Nobody would be one that just focuses on her visions of the future and Rey’s sense of self-worth, and doesn’t try to reveal more about Rey’s backstory. This way, Rey Palpatine could technically still be canon to that version, but it just isn’t brought up or mentioned in the film.
