The first would be great, but probably very difficult technically. The second would probably cause a holy war in the community, as multiplayer RTS enjoyers glorify fighting against the genre's jank as an expression of skill (admittedly it would completely change all micro).

With modern tooling, libraries and such, many of supcoms old technical issues can be address. (plus it now works on linux and mac!)
I think I'm close to a like for like version.
And of course the performance its leaps and bounds beyond what supcom could do, in the replies a few down, you can see a 64,000 unit air fight, and I'm pretty sure i can get that going at 60fps plus!
and end game vs the ai, is still 4x realtime, well beyond what supcom could do.
and of course higher player v player battles
