Yeah, I see your motivations behind all of these choices. I have also said in the past that if you’re gonna do the Machete Order, you might as well do ROTS as the only prequel flashback rather than 2 and 3. I do agree that maybe there are a little too many “flashbacks” that could make the watch through feel a little disorienting, but maybe you could show someone this order and report back to us. If you’re worried about overwhelming someone with too many movies and flashbacks, at the very least I think you could do IV-V-III-VI-VII-VIII-IX.
