The only thing that might need to be improved is that Borg interior shot, where we pull back to see more of the hive. All it should really take is a small color correction though, to better blend together the set and painting.
Yeah, sure, retouch and remaster and whatnot, I was more saying that I think it'd be a mistake to replace the odd, off-kilter 'battle scenes' in that episode (where the Enterprise and cube just sort of stand there looking at each other, most of the time) with a more modern interpretation (The Enterprise whizzing past doing strafing runs and so forth). I think a big part of that episode's charm is its stateliness- the tension comes from the strange absence of action, the utter lack of concern from the Borg.
The 'pull-out' shot of the cube interior actually made me say: "Woah!" when I first saw it- I don't see the need to replace it, beyond the rescanning and remastering of the original plates.
