Seems like a good idea at first blush, but it would make things worse. The airflow at the base of the A pillar isn't traveling straight back in a way that could be meaningfully 'corraled' like that- it's going across at a good angle. So that plate would cause separation & recirculation behind it, and that would make a mess of the flow along the side of the car.
