I would really prefer you not use the Maul fan film footage. It looks really out of place (particularly with the next scene being about stealth,) and I don’t think it makes sense visually - it looks like he’s training on his ship in mid flight, but the ship couldn’t be that big because its scale is established when he lands. It’s also unclear what he’s pushing buttons on the display for - is it involved with tracking the Jedi, or this weird pseudo-flashback training scene?

Maul is really cool (relatively) when he’s introduced in the original film because he’s (relatively) so mysterious, so showing him flipping all over the place with a fully lit lightsaber blocking dozens of shots in front of a glowing blue display seems like way too much, too early, and doesn’t really add to his character. The flipping and lightsaber skills are already established in the original film. The problem with his characterization was never that there aren’t enough scenes of him using a lightsaber, it’s that those are almost his only scenes. Not to mention the actor has a different head and facial structure from Ray Park, though that’s a minor point.

With that said I’m really excited about this edit and I think it’s more ambitious than most. The few times I’ve tried my hand at cutting the prequels, I usually ended up at the same structure you have: two films, mostly killing AOTC because it sucks, and splicing its good parts into the other two. I love your ideas and your dedication.
