What effect would that pressure differential have on the necessity to provide additional vacuum to the rearward area of the shape in order to maintain proper flow?

It's an interesting thought... I remember reading of an airfoil that used this approach to minimize transonic shockwaves.
IIRC, the suction inlet velocity for the 'after' image was over 78 MPH while the car was at 60 MPH, so I'm not sure you could get enough suction pressure & volume.
Plus, as you wrote, changing the low pressure area might disrupt things downstream too much to get the powered pressure recovery.
