Well, with the programs I mentioned you could load the
SL avatar in them, then project the photograph you have straight on to the avatar's face. Then, all you need to do is take that texture that was projected and it should be stretched like that.
Actually, the friend that told me about Modo's capabilities offers custom skins based on photographs using it. Maybe you should talk to her about it, I don't remember her pricing but her name is Ina Centaur.
