I believe it can work, probably best to start it with a small group (<10) of known high quality contributors who are actively working with you and giving feedback on the process. You are going to be trading your time, creating bounties that are objective, testable and fair. This model is just too interesting for it to never get figured out. I am sure at least one successful case will happen (if it hasn't already) in the next ten years.
