An interesting idea, but ultimately, I see two problems: placement and numbers.

You note in your comments that the squad is crippled without CEs, which is definitely a plus. However, a lot of the special abilities upon which it relies are limited to 6 squares, which means you're very pretty limited in how you spread out your pieces, and there's a good chance that some of your boosting pieces will wind up close to the line of fire. I suspect that in this respect, the squad might fair pretty well against a lot of casual players, but an experienced player will likely be able to force your to reveal your underbelly or be ineffective.

The numbers, though, may be the bigger problem. Okay, sure, hitting for 160 damage is great... but not if you can't hit the other guy! Even with your various boosters, I think that's going to be a problem, especially for the Geonosians. On one hand, the large Geo-swarm is an interesting tactic because it forces an opponent's decisions, but their stats are so low that it might often be worth it for an opponent to simply ignore the Geonosians for a while, or else risk the AoO rather than the Self-Destruct.

There are a lot of interesting ideas here, but I can't help but wonder if it might be more competitive with more focus on a few less of them.

Good luck!
