Is anyone able to do this? Or is it not possible. Would love to see this in-game.

Yeah, I'm using a lot of those to make a faction pack composition for public Zeus. I don't think adding the hidden textures in-arsenal for stuff like uniforms which we can use SetObjectTexture on is necessary, but for things like headgear and vests, it's definitely necessary.

Agreed. There's really not a reason they shouldn't be added. There's other items too I'd like to see added back - but I don't want to push my luck lol
