I feel like this movie needs a purpose in the grander Star Wars saga.
First of all this edit looks really neat!
Maybe it could stand alone- this type of movie, while compelling, doesn’t fit the OT. By that I mean if they made an anthology movie like this people would say “it isn’t sw!” People complained about no crawl…
But more importantly by not connecting it with the originals you can tell a complete story. For the first time a PT edit doesn’t have to end leading into ANH. The dubbing let’s you tell an improved story and change scenes to have a completely different meaning.
For example, what if Anakin dies on Mustafar? Obi-Wan’s greatest fear was to fail a mentor, and he does. He now has to directly confront his fear and kill his best friend. Well, more like leave him for dead. Most PT edits need to warp a bunch of stuff up for the OT, but this isn’t needed for a story like this. It’d be a bit weird if this movie ends with Anakin reborn as Vader but the conclusion of the story told in a traditional English trilogy with all new characters (unless you made an all in one OT Tarantino).
BTW how are you doing this? Are you using a Japanese dubbed ROTS with custom subtitles or are you recording the Japanese lines?
