Also, would definitely re-score the Flashback with AOTC music - preferably the Padme’s Apartment soundtracks, but mixed to fit with Anakin’s emotions (like his Mother Theme).

#Jedit:

One could even incorporate a sort of opening montage, with the focus on Jedi Training, were one could incorporate the Reeva Order 66 opening and cut it before the Clones enter -> Do some exterior shots mixed with the Anakin&Obi-Wan training spliced up (turn some of them into night time to accompany Reeva Order 66 scene) -> and make the AOTC opening be like a “A Day in a Jedi’s life” type of opening. This is just ramblings, but it could work with the right amount of footage, music and tone set.
