You might try playing with Traveler's Vic teen morphs--I think they're available at Morphworld and/or RDNA. In general, the Mil PT girl has proportionately much shorter legs and torso, and is a good bit rounder in the hip and thigh, so it just depends on the body type you're looking for. If you're planning to use multiple, heavily morphed figures, cross-talk might be an issue--others can tell you better than I how to deal with it.
