One of the rules around here is to avoid putting story ideas on the forum itself. It could cause jim problems if he ever wrote a story with a similar concept. I don't think there's anything wrong with something this general, but if you're going to go into more detail, you should probably take the conversation somewhere else, or at least go to private.
As for the monster hunter idea, it all depends on how it's handled. There's not enough detail there for me to say.
