I actually did (responding waaay back to the beginning) make one. It's not going to be much, but it was a Poser morph that willdial (has a gallery of monster mams over at renderosity, if you like that sort o' thing..
Kind of far away. But it's been done at least once..
I know Poser is programma non grata around here, but if you want the pic, I'll try to find it.
