Creating BOM Head and/or Body

[imacrabpinch]

How would one go about creating a BOM Head and / or body so that system skins could be used? My initial route is to simply sculpt and reshape the default SL avatar (that contains original UV maps), while trying my best not to crazily distort the UV. I am assuming the topology of the new mesh would have to match the original? Or is there another way I'm missing.

From what I understand the Topology doesn't have to match as long as you can map it in a way that doesn't look too distorted. I'm not really a modeling expert, but the way I would go about it would be to create a mesh head from scratch, then, create a UV map and tweak it until applying a skin template to your head looks similar enough to the same template applied to the default SL head.
