I did a quick 10 minute experiment with the DE and remastered TC and it looks as though frame blending might help improve the rotoscoping in the lounge scene. The TC has a different aspect ratio which needs a bit of work to get the frames to match but once that is done, I think layering the DE - TC - DE might work. Blend the TC over the DE using the lighten blend mode, which pulls up the figures against the darker background (but also the stars) and then block out the actors only on the top layer to get rid of any stars. There is a slight chance some stars close to the actors might bleed through but can probably mask them individually either a blocks or rotoscoping with wider feathering.

I expect that the new CGI with the much larger window might throw up a few problems but I’m sure they could be overcome them really easily.

Anyway, it certainly looks like this will be possible with a bit of effort.
