Actually that is some of the only footage for ROTJ that could now possibly be used, with a lot of work, especially now with Topaz upscaling AI being available along with better noise reduction software . The rest of the deleted scenes from Jedi go from low quality to less-than-laserdisc quality, so can’t be used. But most of the shots inside the falcon are rubbish anyway. Why the hell are they running through the corridors with guns during the space battle? Maybe one or two shots, if any at all, may be used

That would be interesting.
I think the Millennium Falcon is shown only destroying 2 Tie Fighters in all of the finale space battle. Would love to see a little more Falcon action for the last hurrah.

Maybe change the guns in their hands to some kind of tool or an ice cream maker, if you wanted to utilize that footage for something.
