What are you even saying? If you make a gun that shoots watermelons and looks exactly like the rhino, I hope the barrel is properly aligned with the Cylinder and you don't expect the visible hammer to function as normal hammer or else it's not going to work very well. You can put whatever you want into your example, but it doesn't change the physical properties of the mechanical object in question. For instance, I could not take the Rhino, modify it so that the barrel is aligned with the top, and still expect it to work. It would violently destroy itself in my hands.
