That all sounds great to me. This scene will go in the rewrite hall of fame next to the TFA crawl.
The only point of contention is the current canon novels which state that he transferred his spirit before his body even died in the reactor shaft of the Death Star. At least this way Anakin actually killed Palpatine. It’s only because of his followers that he returned, and then a new chosen one was created.
I think I like the idea that Palpatine returns immediately after his death in ROTJ because if he can be resurrected after 10 years, what’s stopping someone from resurrecting him in the future? Palpatine survives because he has a whole clone operation on exogol prepared for this moment, and without a backup, his spirit has no where to go at the end of TROS and dies for good. But I do like the idea that Rey is a reaction to Palpatine’s return, so idk.
