I've been thinking of making something similar to the texture pack combiner but with the hair mods. Or rather: something where you put only the hairs you like from each mod, and it creates a new esp out of those. So, you'll only have the hairs you like, and hopefully no CTDs.
The problem is my knowledge of how to create this kind of stuff is about zero. I don't even know how to get started. So if anyone else thinks it's a good idea, feel free to take it... or otherwise, give me some advice!
