Yeah that’s been considered. I don’t remember exactly who did it or where’s the link to it, but there is a rough version of a rearranged Exegol opening, where “The dark side of the Force is a pathway…” is replaced with “more than a clone…”, (it also includes repurposed Palpatine dialogue to establish both the concept of the Force Dyad and his plan). The audio itself still needs some polishing but is a good attempt, and anything is better than leave the means of Sidious’s resurrection unaddressed.
I’ve posted a much more cleaned up version of the dialogue here a few times, but nobody’s given it a shot.
Unrelated:
Is there an HD version of this anywhere? Some of these shots seem useable with some background replacement work.
