36 year old, Very flat chested AA, Can I achieve a full C-small D? (Photo)

I am 5'7", 140lbs, 32in rib! I am wanting a full C, small D. My surgery date is July 23, 2014. So far I am going with Silicone, round, textured, unders, 401cc rt, and 435cc Lt. In your opinion, is the right choice, and will this get me to where I want to be??
