Undergeared deathstorm

I was recently theory crafting with the idea of using a gear 7 zMT and NS initiate along with gear 12 zAV, Daka, and zombie. Firstly because it's much quicker to gear up 3 toons instead of 5 and also because one of the most important parts of this team is MT and initiate dying off. For those of you who use deathstorm already in P3, do you see any major issues with this? Obviously i'll lose a little damage from the undergeared toons but from what I have understood is that ventress brings in about 80% of the damage anyways.

p.s my long term plans are to gear up MT for other reasons, but just wanted to know about this to get to deathstorm working quickly.
