I've only done a shouldered tumblehome once, but mine had a concave curve. Glass adhered to the outside just fine. It was the inside that got finicky.
Keep in mind: The exterior glass fibers are a major part of your structural strength. If you break them, you have a much weaker hull - or will need to add a significant amount of weight in overlaping the seam to compensate.
