Dark side territory battles and bounty hunters

I have a G12 zFett lead with G11 88, and the rest were G8 (cad) and some level 70-ish (g7 greedo, g8 dengar). I came very close to finishing stage 4 of a combat (figured I'd try them out since the likelihood of getting 4/4 wasn't great anyway). Only 2 rebs left, one of them hanging on by a thread.
So I think they're quite viable, at least Fett and 88 :)
