There are a list of clans that exist in Yamagakure on the page I have created for it. If you change his last name, that's fine, but there are a few other things I'd consider.
 * 1) If he's a missing-nin and an S-class ninja, he can't be from Yamagakure. They're criminals.
 * 2) Tone him down a bit. There is no reason he should have five natures and a kekkei genkai without a really, really, good reason. Even the most powerful jōnin only learn to use two natures at a time. Madara-like ninja, or shinobi like my Ryun, are very rare products of the ninja world, those this Wiki might lead you to believe otherwise.
