>grabbing the eyelash mesh from some eye mod
eye lashes are textures unless you're talking about the 3D ones for humans.
>adjusting it so they can be put on female argonians
Beast races in the CK uses different eye meshes and tri files than the human/mer counterparts.
>adding the eyelashes to racemenu as a slider
Theoretically could work, but those 3D eyelash mods are based off of human heads and tri-files, so it wouldn't move along with the eyes themselves. And if you're talking about the texture eyelashes, well beastfolk eye meshes literally don't have space for eyelashes.

TLDR; vanilla eye meshes are completely shitty even for bethesda standards. It's a reason why modders haven't tried to touch them.
