I do think a comprehensive re-release for modern machines and operating systems would be really neat. I would even settle (prefer, actually) to keep the original graphics, music, etc.
I would love to see SM 1.5 incorporated, though I'm not sure how they would do it. It would certainly be confusing for new-comers attracted to the WC universe by the new release to witness the
Tiger's Claw change her appearance for one campaign.
The cost to refurbish the games is probably too high to merit such an exercise, but I like to hope we'll see something along those lines eventually.
Clearly, I think it's pretty safe to say we would all like to continue forging new chapters in the WC universe. Nevertheless, I wouldn't mind giving a nice dusting to the original entries.
