CC request: mermaid feet and hands

Hi! So, I would like to make some aquatic looking sims. I want some webbed feet (so not exactly mermaid but shuush, maybe like.. a siren) and hands accesory/skin detail to be separate cc that can be worn together if you want to. Both should copy the colour of the sims skin tone onto them - i.e if the sim has red skin, the webbed feet or hands would be red too - instead of giving the webbed feet and hands multiple swatches in various skin colours. It would be also nice if it could pick up tattoos as well, I have seen it done with NotEgain's sad elf ears which can pick up skin overlays too.

There should be multiple categories they can be found under:
in skin detail, probably as wrinkles, since I don't really use wrinkles
under rings
bracelet
gloves
and maybe hat.
preferably for all ages (but baby, ofc)

Webbed feet/hands look something like this, sorry for darkness of gif:
