Looking for 2nd P3 HAAT Team

Our guild just started doing HAAT and I am trying to add some depth to weak spots. My current P3 team is Dathca (L), RG, EP, TFP, and STH. In P1, I use Zylo, P2 I use FO, and P4 I use Rebels. Without pulling from my other teams, is there another decent team that will work? I heard R2 and Teebo can work well, though I assume I will need to add another 2 tanks. Thoughts? Thanks in advance for your input.
