Do that.
You could have .150 mains and .090 pvcrs that are open to the main well (if for laughs, the power valve vacuum port was blocked off) and the engine will still idle unaffected by the main circuit.
Fuel will NOT discharge from the boosters until airflow through the venturi creates a strong enough signal, of which there is none at idle; it will only discharge if the fuel level in the main well is at the height of the booster fitting in the mainbody.
The fuel level in the main well is the same as the wet level in the float bowl at idle/low speed.
