Hmm, I'm no expert in this, but couldn't it be as easy as defining the new desired item and a merger that creates it? Should be pure xml work within existing systems, no?

*shrugs* You're still burning a camo kit every time you do it on every item.

True it stretches the realms of believability but depending on what the camo kits are made of they can stain clothing so it was a case of it seeming less hassle than adding clothing dyes and using something already there.

The simplest route would just be to turn the camouflage kit into an unremovable attachment, with a "+x% camouflage" modifier although it'd be nice if we could add a value to maps to define the area type for camo purposes.
