I really like the idea of this team make up for battlegrounds. (I wouldn't even try arena).

My ret paladin does really good damage, and I think with dual healer back up he will be even more formidable.
I'm not sure how the mixed healers will work together. Two druids might have worked well, I figure I could have
kept the two druids mobile popping hots. Controlling the druids with my nostromo d-pad and my pally with the mouse.

The shaman might add some utility, being able to do big heals, and being healed by the druid (and pally if necessary).
A tremor totem will be slightly better than nothing, but he wont be at all mobile. Then again magma totem, nova totem,
Fire elemental occasionally might be nice.

What do you think - Workable?
