I experimented to transfer a morph of genesis to G3F and yes it does seem to work :). Though the process does seem to be pretty straightforward but I have not yet tested it on many characters. I will try to experiment with some more characters tomorrow (its already early morning here). If it works indeed then I will post all the required steps here. And yes, if it does work then there is a very good chance that this method will even work for Victoria 4 figures also.

The character in pink outfit is genesis while the one in black is G3F.
