Hedgesmfg, I like what you’ve layed out in your timeline, especially the intercutting of the 03 footage and the Early SoM bits.
I’m currently toying with the idea of having the only 03 footage be the Dooku/Grevious training duel and subsequent convo with Sidious, ending the use of the footage with Yoda seeing the fleet approaching Coruscant. Then my “Day One” title card will play.
I think pacing-wise intercuttung the Battle Over Coruscant with the Mandalore attack isn’t a bad idea, it would keep the film from going too long without seeing Ahsoka. I might have to toy around with what I’m doing somewhat.
I do think stylistically my edit will feel different than the others, as I’m doing the “countdown to Empire Day.”
