Not many, and frankly they're not very good. Not trying to slander the artist- the way the engine runs, it really can't properly support dynamics 'not close to the bone' (so to speak). Well- some bending at the joins isn't right still...
Looking through my stuff I see:
V4
Crom131's BBW Goddess
G2
FWSA MeMoo HD
Big Beautiful Genesis 2 Female(s)
(yes- that's the actual title of the model(s)? on the Daz site)
These should be pretty easy to find. Let me know if you can't.
For males- no idea. Good luck looking. 'George' is out there but he's G3 I think- seems pretty well done but no idea how he looks posed.
Anyway, as Phoernik said, using morphs on existing models is probably easier/more flexible. Good luck whatever path you choose!
