Are you referring to the entire shift assembly that looks something like this:
If so, that's a piece of cake to replace. Replacing just the thumb lever is harder.
Shifter compatibility isn't much of an issue for double chainring setups. You might get less than ideal trim options and lever feel, but you'd be able to make it work. The nice thing about this generation of Campy shifters is that the front uses a micro-ratcheting mechanism rather than indexing, so you can put the derailleur any place you want it. Makes it easy to use with a triple too. There may be some lower level models (Mirage, Xenon, maybe Veloce) that don't do that. The newer Potenza/Centaur/Veloce shifters don't work that way.
