Already possible, although it requires you to actually script the weapon. More on that here:

If possible, you should make it so you can change the PAP camo on weapons with C_Model support.

I wanna do this, but what submodel is the arms change with each model, on half the weapons the arms would become the camo instead. Haven't thought about c_arm models, they might actually work.

The last thing is the PAP sounds, you should be able to change the PAP sounds, like the classic sounds, the BO3 sounds or none

The sound is changeable by manually changing the sound file but keeping filename and path. They won't be changeable in-game with a setting.

Ok then, never knew that... well thanks for letting me know! I wanted to get into scripting anyways
