Since we’re talking about a little reordering of episodes, I thought about the clone armour. The Phase I armour (which appears in episode 2) is used up until the Citadel/Mon Cala episodes, where it appears alongside the Phase II (which appears in episode 3), which then becomes the main armour.
Oddly, Phase II does appear in ARC Troopers (not a suprise, that was originally set a little later), but it also appears in Clone Cadets, which I thought was early in the war. I really think we need those episodes up first.
Canonically, the armour had a phased rollout, so I don’t personally have a problem with the idea that the Clone Army was launched in the Phase I armour, whilst they gradually upgraded the forces with Phase II throughout the clone wars, but I can understand if people have an issue with it.
We really should open with the Rookies arc though - it gives us some meat for Ahsoka’s light intro, makes us care for the clones, and also makes sense that the Separatists would target Kamino early.
I always got the idea that Phase II armor was worn only by ARC Troopers during the earlier half of the war and later spread to all the ranks in the clone army as the war progressed. For example, in the Citadel arc Fives and Echo, after they become ARC, are the only ones who have Phase II armor while all the non-ARC ones wear Phase I. So having the Domino Squad at the beginning of the series wouldn’t create any continuity issues.
