How about this
Class 6 - 40 (8 - 5 team districts. Only seeds #4 & #5 play first week of playoffs - class 6 then ends same time as all other classes)
All other classes - 56 (8 - 7 team districts. #1 gets bye - no more of the dreaded #1- #8 playoff games)
That takes care of 320 schools
Less differential in class size.
Genius!
The Class 6 and Class 5 lobby will never allow it.
