Hi there !!
There are some substitutes, but not as extensive as the one you are saying.
You can have Book of Steel/Water.
ADAM for NCR ranger/desert ranger/riot armor.
Spice of Life (used it, didn't like it as much as Wastelanders Clothing Hires honestly... but like you said, sadly it was removed), this should be the most similar one to WCH, sadly you have to mod your game a bit further.
Also there are plenty Overhauls made by dragbody posted here.
In general you have to go and look a bit to see what really catches your eye, both here and on the nexus page there are a ton of mods for clothing and armor (armor mostly TBH). Hope I was able to help you a little bit at least
.
