You can't force a school district to build a new high school. Why in the world would you think that anybody has the power to do that? Class 5A would split school districts into different classes, but my example would have 5A with four 6-team districts and 4A with six 6-team districts, meaning that all of those schools would have four slots on their schedule every year for non-district games like SC North vs. East and West, W'loo West vs. East, and the DSM area schools could rotate playing one another based on who they actually wanted to play. If DSM East knows they aren't competitive and would rather schedule Indianola than Ankeny, then they would have the ability to do so. Solves both problems at once.
