I do like the look of it. Sorry I forgot to comment before. I like how it isn't all that dependent on winning initiative (no Cunning/Opportunist attackers, no glass cannon problems). The crazy psuedo-mobile for Jango is plain awesome. Bringing in a cart allows Kota to be almost as deadly as he would be with R2 Astromech, plus it increases your CE range (although it's fairly minimal). Although, I think sometimes I would be tempted to bring in a Cart and a Rauntaun (more for Spotter than for Recon), which might leave you a bit tight on activations.
Might also consider using a Rebel Leader and 3 Mon Cal Techs for reinforcements. Get some crazy Spotter action going.
