There are several models of this kind already made of Posette, the problem is that most of the texels generated are wasted as they don't give the model any additional abilities (dimples, wrinkles, crow feet, etc.), they just increases the memory use and the rendering time. Selective generation of subdivisions to allow additional human features on the face and body is much better. Download the Vicky and Michael templates and see how the texels have been placed on them. Making a 3D model high rez is not a problem, making it low rez while maintaining its usefulness is.
