This reminds me of a squad I played in a 150 event at my lgs and I went 3-1. I actually lost to yobuck due to some bad positioning on my part and jarjar.

51 Count Dooku of Serenno
36 Darth Sidious
34 IG-86 Assassin Droid x2
11 Human Bodyguard
9 Battle Droid Officer
9 Ugnaught Demolitionist x3
(150pts. 9 activations)
I do like your take with the keldors. But I am not sold on san hill with this squad design. The duo of activations can be key. Out activating doesn;t always help against yobuck. Sometimes yobuck leaves the squad in safety at the end of the round and there is a single key round somewhere in the middle (usually right after an r2 tow and a yobuck gallop) that you have a shot at yobuck before jarjar gets swaped in.
After thinking about your design I want to try and work a keldor in, but I am not sure how.
