Don’t mind, I speak jumbly already. XD The idea was to take the BD version, then roll it back to the 04, then roll it back to the 97SE, then roll it back to the OTVs - a progressive despecialization using everything available.
For example in ESB I would probably use 97SE footage of the Emperor, and I’d use some 97SE footage of the end of ROTJ, if enough of it survived to blend in with Yub Nub. And if 97 footage is higher quality, also, so be it.
