I have always wondered whether the warlock would work for the monk: you spam flurry of blows like EB, you get two big anime moves (like the spells) per short rest-maybe from the subclasses, and you get to customize things with something like invocations, so you can be wild like Jackie Chan, a ninja, or something else, and like the warlock, these are more for fun or out of combat (or in the monk's case to avoid combat) than for combat power. Or if you wanted to move more power into the invocations, you could have it so that the monk can deliver a touch spell with an unarmed strike, and the monk can pick up touch spells via invocations.
