I think the key mechanic being leveraged here is the fact that Mana Wall basically gives you (potential access to) 75% damage reduction: 50% from normal -damage gear, and 50% from Mana Wall. No other tank can do this.
The major drawback is in that you can't actually cure a Mana Wall tank, only various forms of refresh (plus convert). That's ultimately the dealbreaker; even if you solve the enmity issues, the current realistic refresh max is around 15/tick. 15/tick regen (and no cures) for a bloodtank, even with 75% damage reduction, is not even close to a sustainable strategy.

I've looked the only other way to gain mp that i've been able to find is whm's merit skill: Devotion and even with it maxed out its recast time is 10 minutes. So yea there's no way to make the "mana tank" idea viable.
