The beauty of asymmetric pins is the pedal shape is the same and, as noted in my photos, it's easy to keep the contact patch the same no matter which side is up.
The problem with a medium + large pedal is that when it's flipped over it's a large + medium pedal. It's a bit like one-sided roadie clip-in pedals. It would work until you totally need to slam in under pressure and then they're never in the right position.
