I’m doing something similar, but I’m merging the DVD/BR into a hybrid version. If you are going to be complete, I’ve identified 5 different versions of the original film (original 77 premiere, 77 general release, 81 rerelease, 80’s home video, and 90’s home video… And you could add the GOUT for a 6th version). There is the 75 mm version of TESB that you’d have to recreate, And a few other variations that don’t exist in high quality, such as the 35 mm version of AOTC. I’m sticking to just the major version unless I can use angles or something to include them.
