Things I would like that are technically possible but would be a bitch to pull of

Making the Droids Clones and Clones regular soldiers. Maybe have the suggestion that The Droids have Cloned Brain matter of something? Deepfake all the Clone faces or even Deepfake the droids?

Make kid Anakin look Padmes age. Voice pitch lower, Deepfake face, make him look taller through shot selection or increase his size somehow with rotoscoping?

Have Owen be Anakin’s older brother. Deepfake someone for a few brief scenes, get other movies Joel Edgerton starred in and rotoscope him? Dubb him in ATOTC?

Make Grievous and Maul the same person. Dub Grievous but then also add a more climactic showdown between him and Obi Wan instead of just Obi Wan lamely shooting him through animation?

Add Dooku into TPM and set him up as either the bad guy or a rouge Jedi destroying the republic because the Sith have infiltrated it?

Making Naboo Alderaan and making Padme a relative of Bail

Take out C-3p0

Having The Ewoks in ROTJ look completely different or be Wookies through Deepfakes

Have The Second Death Star be some new superweapon

Redubb the whole Obi Wan-Luke conversation (no more "from a certain point of view"bs)

Have Han,Chewie and Lando Die (reediting? Not sure where we would get Leia’s reaction shot)

Have Luke walk off into the sunset (maybe Mandalorean footage?)
