Agree that the best path is try it as is, get the engine running well statically then start a test sequence with slowly increasing aerobatic maneuver intensity to see if the flow through the cowl is adversely affected... (with deadstick altitude always available )

With any luck, the cowl will act as a plenum, providing positive pressure to the carb inlet with most maneuvers .. with bad luck, the flow will be so fouled up that the carb will see negative pressure, and the engine will respond accordingly...

Keep us posted!!
