All you'd succeed in doing there is ensuring that all elite sport is male.

No, you would have multiple elite categories. Some of those categories would be dominated by athletes currently categorised as "male", some would be dominated by athletes currently categorised as "female" and in between there would be categories where the winners could be athletes from either of the existing categories.
