PS: No, actually scrap that. Scaling up the areola on the flat chest will make them protrude when there's curvature. Adding a bulge might even that out a bit, but in order to fix the protrusion one would have to pull the areola inwards. Might not actually be that big a problem in practice, so I'll just wait and see.
