Well the tall Pro is about the equivalent of the average Buck, with the original Pro the same as the shorty, so an even taller Pro would have value, at least in the Star Wars line where there are Buck figures with height precedents, might work out with just the 2 in the Joe line because of that line being all Pro figures.
I'm hoping that will be the next Pro body... 3 heights would work very well; and approximate the scale available with the Buck, but of course with improved articulation and aesthetics.
