I don't know about all three. They'd have no competition, they'd steamroller everyone in a week and then it'd be over. Nobody wants to see Dreamer, Christian and Finlay take them on and win. However, it would make it more interesting if either Henry or Jackson becomes in cahoots with Kozlov after his most inevitible title success becomes a reality. That way to get the title you have to go through a massive unit and then also Kozlov, who will be "undefeated one on one in pinfall matches on ECW" or some other ridiculous streak.
Two of them plus a real cockpiece of a manager, (i.e. not Tony Atlas), would work well in the midterm.
