That would be the very definition of infringement. You're not attacking the right itself, you're just trying to nibble away at the fringes. It's like saying, you have the right to speak your mind, but you don't have the right to express distrust or criticism of the government. If you do that, the government will punish you. You have the right to keep and bear arms, but not arms that satisfy this list of cosmetic effects. If you keep or bear any of THOSE arms, the government will punish you. Same thing. Just keep and bear OTHER arms, ones the state approves of, and just express OTHER ideas from your mind, ones the state approves of.
