Ok, in football, there are 5 classes and 8 regions. That means 160 teams make the playoffs.
In basketball, there are 3 classes and 16 districts. That means 192 teams make the region.
You already have more teams that make the region tournament, which is essentially where football starts.
If you had 5 classifications, then the math would be
5 classes, 16 districts, 4 teams per district - 320 teams make the region. Way too many.
You want to give people extra chances? Go back to having sectionals instead of substate. Then the region consolation game means something.
