Thank you for your kind words, momodot.

The picture above shows my fat M3RR.
It's not a hybrid.
I just remorphed M3RR's body to look like Rikishi's and then re-rigged him.
He now takes Rikishi's poses and can wear Rikishi's clothing.

The default DAZ face morphs are mostly broken due to the new face shape, but I'm used to making my own anyway, so no big deal.

Body and face were morphed In Poser 7 with magnets and especially the MorphBrush. The grouping is still M3RR except for the leg/buttocks.

It's way from perfect, but I still doubt you could get a similar results with even the most elaborate "morphforms".
