No, the regulator will send the excess back to the tank.
The pressure between the pump and the reg as seen by all the carbs SHOULD be what pressure the reg is set at. You could fit the gauge at each carb in turn to prove this.

I wouldn't do a bypass reg setup with a mechanical pump since the pump will always be "pumping" unlike when the mechanical pump "idles" when fuel pressure is up.
