This sounds great.

Regarding the upscale of the deleted scenes:
Considering the fact that we have hi-def footage of our actors, wearing the same costumes, in the same movie, one might also consider more advanced machine-learning techniques instead of “just” an upscale using a “standard” neural net. By clever combining, overlaying and inputting data, quality might jump quite a bit.

Also: You might want to contact a person named Owen Davies, going by “ODVS” in the internet. He made great strides in upscaling shitty footage in recent years and is involved in many great projects, including the WingCommander4-FanRemaster and the StarTrek:-Borg FanRemaster.
