Ah, I hadn't been thinking in the direction of rule 34. On the other hand, there are many disabled people who want their sexual partners to be attracted to them not despite their disabilities, but want their partners to be attracted to them as a whole, including their disabilities as part of who they are.

But sheesh, we're talking about dolls for kids here, so rule 34 doesn't even remotely apply (except maybe in the way that, alas, rule 34 might apply to “abled” dolls, too: a doll fetish or something. *sigh*).
