I put together what Districts would've roughly looked like if the classes were broken down with Class 6 having 48 and Class 1 having 48. I didn't number the districts according to geographical location because I would propose after the district champions are crowned, to then seed 1-8 and have a bracket from there. I know travel becomes the issue, but it would only be for 2 games. You may get 2 top teams in a district, but I think for the most part year in and year out the best teams will be playing at the end. Let me know what you think.
Cut off for each class:
Class 1 - 185
Class 2 - 322
Class 3 - 497
Class 4 - 819
Class 5 - 1211
