This might not be the best squad to take on the droids, but i think it would do really well.
I would spend the first few rounds building up force points on vader and palpy while getting my Kel dors and Geno into position. then i thrawn swap the geno with vader and hit with either a sith grip or LS throw 5 (depending on weather he is grouped close or not) with LS throw 5 i have the potential of doing 60 damage to each enemy i hit with a +19 att. Then next round i take first turn and swap vader out again. Rinse and repeat.
