I’m really digging your idea man. If you don’t mind me making a suggestion, I also think it would be interesting if you were to use some genre music in certain places as well. Tarantino occasionally does this in his own films. For Bill’s death scene, he uses Ennio Morricone’s track “The Demise of Barbara and the Return of Joe” from Navajo Joe. At least one Morricone track is almost a MUST if you’re going full Tarantino.
I feel something from Morricone would be appropriate for something like the finale montage, when Obi-Wan takes Luke to Tatooine and such.

Another suggestion I really wanted to throw out here would be the use of Toru Takemitsu’s powerful and haunting score for Akira Kurosawa’s Ran. I think something like this could fit well with the Rumination scene or when Anakin falls to the dark side. Kurosawa’s Throne of Blood also has a pretty haunting soundtrack. Just some thoughts though!
