Weapon customization

Sorry if there is already a thread about this but there's a bug or glitch with my search forums. When it says 'type the characters in the image' or something, no image pops up so anyways, I'm suggesting weapon customization. LOL, now I know what your thinking; it's Call of Duty'ish, but I think it would make the game more fun than it already is. With weapon customization, you could change the colors of your guns and add engravings or little pictures or write stuff like your nickname, your real name, lots of cool stuff. And MAYBE add weapon scopes. Weapon scopes are only optional, since I don't really care too much about it.
