Wow, I really like that build! Looks like a very fun character to play.
One thing I'd change is the weapon though; while the idea fits the character perfectly, the damage is just too low to be of any use, you'll never get past any kind of armor, in fact it's so low that most characters might just be able to soak any damage you can do.
Instead I'd recommend spending those points to increase your pistols skill. The Pulsar isn't bad, but I much prefer the Defiance EX; its damage is amazing and it can be used as a melee weapon too. Higher pistol skill will allow you to be pretty good with a heavy pistol too, I'd carry one just in case you run into a situation where violence is the only option.
Besides that, imo the Commanding Voice adept power is simply too good not to have as a Social Adept, especially considering how cheap it is. I'd recommend dropping one of the other powers (Glide, Great Leap...) to pick it up.
Also, I'm not sure the Stealth spell will do you much good considering your character has no Stealth skills whatsoever. Sure, you'd be hard to hear, but that's of little use if you're as easy to spot as an elephant... Wouldn't Improved Invisibility be more handy to make up the lack of infiltration skills?
