Attached Link: Aiko Toon

The Poser figures closest to what you seek possibly are AikoToon and Hiro Toon at DAZ. They are head replacement figures for Aiko 3 and Hiro 3. I used to use Shazam for such commercial work... it was a toon version of V2 that had a male morph. You could also check out the free Poser 4 figure varients by pitklad... they have scaling features that permit creating bauble head type toons. There was an overly exxpensive product at Animotions that was called Super Derformer or something like that which was a magnet system for turning Poser Millenium 3 figures into toons. I believe that in the "morph form" section of the Body control for V4 and M4 are dials for tooning the figures heads, hands and feet. Maybe you could use V4 The GIRL or G4 or whatever it is called to make both toon men and girls... I don't know. I recomend the AikoToon and HiroToon for an "Archies" look though... not as bauble headed as other toons but still very toon. Someone made character morph sets for them... the only trouble is not much texture support but maybe you want "plastic skin" anyway.
