You're not the only ones to have this idea. There's that water pistol FPS on Wii Ware, and the Fireman shovelware game that's pretty good compared to other shovelware.
This is how I think it would have to be done: something like Unreal Tournament with less blood, intuitive controls, local online multiplayer (like Mario Kart Wii), plenty of game types and ranking only among friends. Bots would be crucial.
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
