I say let Hunico keep it, kharma and just desserts you know. Hunico was the first Mistico and had his gimmick stolen by the other guy. So its all fitting that Hunico takes the Sin Cara gimmick on to make the big money selling merch, for a mania match vs Rey, and maybe even headlining the rumored CW show. Hunico is getting what he deserves now, and unlike Mistico 2, Hunico paid all his dues and did everything right in developmental like learning English and how to work a wwe style.
Camacho should just be given a new partner to keep up the thug tag gimmick. He's a relatively big guy that can move, so someone like a JTG helping him along wouldn't hurt either guy.
but boy Triple H's first two signing bombed out right in Kong and Mistico. Both just stole money, while the other part timers he's brought in have been more helpful
