I would have tried to explore that option before leaving completely. I know two professors who have switched fields, one was physics professor who did work in string theory, switched to genomics and got position at a medical school. Another was a CS professor who actually went in to math. You sometimes see CS professors who have degrees in pure math just browsing different department's websites.
