I would imagine they’re going to ignore this whole idea and try another soft reboot. If it ever gets to production.
Probably for the best. Considering how divisive and bizarre a lot of the choices have been, another story with Rey will go down easier with a clean slate. Ridley has charm and can deliver in the role. I like Rey, enough to wish Episode 9 never happened to her. Hopefully she will be gifted better material this time*.
(*if this film actually crosses the finish line, which you cannot count on)
