I've been thinking of applying agent based simulations as a new way to measure risk. That's a bit different than what you're thinking of but I think it would be self-consistent, or at least the way I understood it.
Agent based simulations would probably be a very excellent approach. Unfortunately, the system is highly nonlinear and quite chaotic, so you'd have to do some work into engineering dissipation into the system to keep it from fluctuating wildly.
