As I understand it you are proposing something analogous to the weight classes in sports like boxing and power lifting. The idea would be to classify people not based on skill or ability but something more like physical potential. I see a few problems with this: 1) it would be pretty hard to measure this ‘PPS’ in any fair way. 2) it would be a harder sell to convince people the lower ‘PPS level’ teams were worth watching and funding compared to ‘women’s teams’, which would be bad for female athletes. 3) there’s the question of how it would interact with the US program of sports scholarships, which AIUI is based on sex.
