I believe Kevin Heise et al proposed a system to the High School League over 5 years ago that would classify schools by historical soccer success rather than by attendance numbers. As I recall, it went over like a lead balloon.
I don't know what the league's reaction was back then, but I could imagine that the other sports' coaches would say something like: "If the current class system is good enough for all of the other high school sports, why does soccer think they are so special that they need a different system?"
