I was actually toying around with the idea of making Attack of the Clones episode one just like you mentioned with some flashbacks added. Could be dream sequences for Anakin even. There’s a deleted scene of him waking up from a dream while they’re heading to Naboo that could be added to give another flashback even.
But my idea is for the trilogy would be Attack of the Clones E1, Revenge of the Sith E2 and a movie edit of Kenobi as E3.
