I'm not sure if I have the discipline to see it through, but I'm going to give target training a try. When I fed him this week, I paired the feeding with a target (a paint stirrer with a circle drawn on then end). His food response so far hasn't been a problem. He hasn't struck at or bitten me yet. I'm just sympathetic to the non-invasive approach. For the same reason, I'm also giving choice-based handling a try.
