Actually, with the new, slightly altered, mission statement of making v3.0 something like what a proper official BD release of the unaltered versions would look like, I was thinking about using soft subs, which would match the theatricals as close as possible in shape and size (can subtitles be rendered from images - I mean, if I cut the subs directly from one frame of a 35mm scan, could that be turned into a soft sub?) and have seamless branching for the crawls/credits of the foreign language versions.
Alternatively, seamless branching could be used for the subs as well and should be easy enough to do for Greedo but for Jabba, i would be a pain in the a.

I’m hoping to work directly with NJVC for the official release this time, so it would depend on what he thinks he could pull off.
