That would be pretty impossible since the only way he wont be able to heal himself is decapitation, and since his bones are covered by adamantium, it is pretty much indestructible. There was one point where he was pretty much burned to the metal skeleton, and he healed himself within minutes. Even in X-men 3 at the end when he killed Jean Grey/Phoenix, she was tearing his skin apart, showing the adamantium, he was able to heal. That might be a no decision..
