Reduced to anatomy

Is there any material on transforming/reducing into part of their 'anatomy'?

For example, a woman who transforms into her own disembodied breast(s), or a man who transforms into his own disembodied 'lower horn' (to use a Futurama euphemism).

In general I'm thinking of just transforming such that the remaining part is normal sized, just without a body behind it, sort of like Thing in the Adam's Family, but another possibility is sort of a BE/SW where the mass of the woman is transferred entirely into her breasts leaving no woman and just a giant version of her breasts.

I tried searching, but couldn't find anything on this, and I've never seen any material on it before. It's an idea I've had for several years, but my artistic talent in that area is limited to mediocre photoshop work and no process.
