Of course, MS knows that and they have already proven they have no problem reusing villains in a new context.
Stane's dead, depending on what happens in IM3 Mandarin may or may not be dead too. Beyond Madame Masque and Ghost I don't see many other film-worthy IM villains.
I just think the day they're stuck with using either Blizzard or Melter it's time to do a soft reboot with one of the major villains' deaths/histories instead. They do it in the comics all the time.
