Yes, please! Although, I’m more interested in the same principle for a serpentine tail. Did purchase the Gorgon, which is for Genesis, but the section at the hips was a lot fatter than expected (more so than on the promotional images) and I was really looking for something sleek and, well… Mermaid-like - except minus fins!
I’ve got a suspicion that it’s because it folded the Genesis legs up, in the same way as versions on Second Life do to achieve the same effect. Hiding the feet becomes an issue at that point, which makes it bulkier. Just a suspicion, though.
If you don’t mind painting on fins (or adding if you have them as props), the Gorgon might work for a mermaid, however.
Would also like a variety of tails which can be fitted to a humanoid figure’s spine (both with and without barbs/forks/spikes, because some people like those and others, like me, just want a slender tail) without hiding the legs, to help achieve a properly demonic look. Especially if such products came with a variety of different skins/textures, just in case the default one didn’t match up with your character’s existing one.
