This is just based on speculation & random bits I've read on this forum, so I could be wrong. But I don't see why it wouldn't work if you limited boost lower for pump.

People in the miata community have been trying at limiting boost on superchargers for a long time, with various valves, restricors, even one I saw with a wastegate-looking setup. None actually work well that I know of. The proper way to control boost on a supercharger is by using the correct pulley.
