So you can set up a million experiments which all show physical laws not being broken, and come up with a respected theory that there is no supernatural.

So you could say that the belief in the supernatural is falsifiable. The problem with your wording is that non belief in the supernatural is non falsifiable is just saying the same thing.

Another things to keep in mind is the difficulty in proving a negative, so I would imagine that it would remain a theory instead of a law, but I'm no expert on scientific philosophy. And of course for me the belief in the supernatural is an act of faith, I don't feel the need to defend it scientifically, nor would any number of experiments change my belief.
