I don't think I would do any major rules changes, because I think unless you wait like twenty years to do this you'd only be angering a very vocal group of players by rendering their collections obsolete.I would think you could add rules by incorporating new terrain, glyphs, figure powers, etc...in much the way that Uncommon Heroes were added, or Treasure Glyphs, or Destructible Objects, and so on. New stuff enters the game without ruining the old.
That said, if this were just a total fantasy world where I could redesign the game from scratch and not worry about rebuying my old stuff, I'd want nice thick figure cards with original painted or comic-style artwork, not just figure photos. I'd probably change the part of the card with LOS stuff too...not really used that extensively I feel.
I'd also change some power wordings, make sure all errata were covered on the card, etc. Probably make Flying and Disengage into symbols instead of needing tons of text...maybe just those two powers though, nothing else...they are both common and wordy.
