Is there anyway to edit "special weapons" in the game style. for example if I have kitchens sink, and create game scheme based on it, all armory i see is weak weapons, but when i start playing i have all the super weapons. My point is, is there a way to setup my own weapon scheme choosing from all weapons.

Short answer: No

Long answer: Yes, but it requires hacking the game code, which is very difficult in the full version (as opposed to the demo)
