I personally think the definitive best way to pace it would be:

-> Original opening with Padme assassination attempt
-> Deleted Scene of Padme at the Senate Hearing (it’s a good scene on its own, and it will help calm down the intense opening for a smoother transition
-> New establishing shot (fanmade -> Coruscant Exterior, a Jedi-worthy, subtle soundtrack
-> AOTC Flashback incorporation (color graded, Anakin’s voice pitched down, deepfake incorporated)
-> Chancellor Palpatine’s Office, Padme and Mace Windu talks -> suggestion of Obi-Wan and Anakin to assist
-> Anakin & Obi-Wan in elevator

This introduces all main and side characters (except Dooku) in the opening ten minutes, would provide smooth transitions between the hard opening, but most importantly; a time span of what could be a full day before we see Anakin & Obi-Wan again after their Flashback scene, so for the audience to disregard the subtle changes in actor’s age and differences between the two very different shooting schedules.

My two cents.

AGREED
