Anyone try this yet in Legion?

I think I'm going to make this my fun team. The amount of damage reduction (smite, PW:S, passive) they have might make cloth tanking doable. Their AoE is going to blow for sure, but might be able to topple single pulls pretty quick w/ penance. That's the theory anyways, they're all 90 right now so it'll be a while before I can figure out if their damage / survivability will be reasonable enough by stacking crit + haste.

Plus, it's easy enough to sub a pally or DK into the tank position for RDF etc.
