Not even a wash in terms of effectiveness, well worth it.
Tankswap? Sure. Main reason being 15 seconds of tank dps is worth quite a lot. Why wouldn't you? They're right next to one another anyway.
Other stuff: try and 2-heal it. After 3 minutes the fight is basically over in terms of tactics once Sul is dead, you can just swap to empowered one everytime with everyone. Have best cleavers on Sul, preferably melee like frost dk's. Assign dps to swap to empowered, preferably dps with not hard-hitting abilities because of the reflect. An elemental shaman for example could easily almost global himself with elemental overload procs. I'd say 3 on Sul fulltime, 3 to swap should be perfect. The only tricky part is that your 3 people who swap to empowered will need to find a soft spot to not put too much dps in empowered one and not too little either, but that's just something you'll need to find out by pulling.
