I've seen Satanica megamorph for david and stephanie. Search on renderotica.

If you wish more Disney like figures, try Lady Little Fox characters: Koshini, Ishiro, Krystal (with Penelope), Kiki and all theirs CDI morphs. CDI toon morphs for Aiko3 and Hiro are great also. Famous but forgotten Daz The Girl (with Boopsie) is queen of toon charactes.
They are not Disney but similar style as much as 3d can be.

I do not want give here links to commercial sites but figures are easy to find on daz3d, faerie-dreams
