I can’t speak to the feasibility of some of your more radical ideas, but I really like opening on invasion, the droid/neimoidian hologram scene on the planet, and into the Jedi. That’s probably our most bombastic and interesting opening for this movie and saga.
Droid and neimoidian dialogue is editable enough, so we could likely do something with that scene to flow naturally into the Jedis’ appearance.
I think the holy grail for me would be a transition shot from space down to the planet (or from space to neimoidian base ships launching landing craft), to give editors that alternative opening to build around.
