Mods to allow multiple options from same catergory?

I have a bit of an issue with how EA produces occult based content, where something that could very easily be a genetic feature is "artificial," being placed in the tops category (the mermaid torso scales). The one which frustrates me more are the makeup additions that came with Get to Work for Aliens, which I feel would fit so much better as skin details, however skin details cannot have the opacity edited in CAS whereas makeup can.

I love the Alien eyeshadows and blushes but I see them as genetic skin patterns than makeup, and I would love to be able to have multiple of the Alien "eyeshadows" in use on one sim at the same time to create more unique combinations of alien features, including the ability to make some features more/less bold than others.

I have converted all of the eyeshadows and blushes to skin details covering various different skin detail slots but it removes the ability to make them more/less pronounced.

Sooo what I'm looking for is either

A) a mod that allows skin details to have customisable options like the makeups now do

B) a mod that allows multiple eyeshadows etc to be used in the same outfit, together.

The image I have added shows one of my alien sims wearing pink eyeshadow alongside 2 types of GTW eyeshadow, in white swatches, which I converted to two different skin detail slots. These two GTW eyeshadows are being used as an alien genetic feature instead of makeup.
