Cage - I was thinking that your refering to a memory leak as something preventing completion of calculations.  Anything that would ever work, say overnight(?...), is fast enough for me!

Spanki - I just don't theorize your limits.  Call it wishful thinking or optimism, but human form, is Human form to me, and  I should suspect that whatever the problem is, numerically, when it's solved within the limit of what you would consider Human, then it should be solved for everything less.  I could see difficulty if the problem started with a given geometry set, but then ended in the new creation of an unknown figure(With likeness' to photo referances or random parameters,) but we are starting and ending with constants.  So,  I still do'nt understand what the big todo is with turning V3 into a sphere, a square, or any other primitive.  I would just start, and keep returning to, her center; to push each vertex away, in the direction it is from her center, with Rays, until each vertex has been moved, to an equal distance from the center.  The mesh may be heavy in some points but there would be a lot vertexs, still.  I do'nt see this script working much different, exept that the vertexs could stop being pushed when they reach; an enlarged, centered, copy of the target mesh.
