Actually, because the two mikes would be facing forward with element NOT
flush with the pzm surface, the pzm effect may be small.

However, I did an experiment by placing a small plastic barrier between two
forward facing MKH 20s and found that this alone produced a pleasant
stereo/binaural effect, so I think the concept would work.
