It would be completely separate from the normal character creation. Basically, you're in the CC, right? And then you hit the boob option, and it takes you to a completely different system, where you design your own boobs, with tons of options. Not just size, but shape, real or fake, texture, nipples, areola choices, jiggle amount, the works. And then you can use those designs and put them on your characters. >:3
