No, I don't think so. Taller/shorter pedals don't change the size of the pedal circle at all - your foot is just higher at the top AND at the bottom of the stroke with these pedals. So the only real effect of having these on both sides (i.e., equal-leg-length people) is that you'd have to raise your seat a little to get the same position. That and (maybe) you'd get a less-stable pedaling platform - if you believe the proponents of Hi-E and Dyna-Drive pedals that substantially lower your foot relative to the pedal axle.
I remember '84 Olympic Road champ Alexei Grewal swore by the advantage of the lower foot placement with Dyna-Drive. Not that racers really know anything about what really makes them fast - this could well be superstition.
