I’m considering making an alternate extended version that includes the '03 Clone Wars Attack on Coruscant as a cold open, and incorporates some material from Bad Batch Episode 1.

For Bad Batch, that would probably be the Order 66 sequence, their viewing of Palpatine’s Empire Day speech, and a sequence that could be incorporated into the epilogue. Any suggestions on that front would be accepted.

EDIT:
After toying around with some stuff, I have decided that I’m gonna move the Grevious arrives on Utapau scene to the beginning of the film. The dialog will be altered a bit, and it will give the film an opening scene on the planet, get the ball rolling on Sidious’ plotting right away, and it will still serve the same purpose of showing where Grevious is, while also making it clearer that Palps was just waiting for the right moment to give him up.
