For this to happen, I believe UIL would first need to cut down its number of teams that come out of the 32 districts. Right now it’s 4 teams per district.
The two larger enrollment schools into 6A Division 1 and the two smaller into 6A Division 2.
If that number was cut to 2 teams per district, that would allow for the 6AD1 and 6AD2 winners to play each other for the 16th game to decide just one 6A state champion.
My only issue with that is I believe we would see the same two teams coming out of the districts every year with no possibility for upsets or disparity in playoffs.
Maybe I am wrong but I think that would mess up what makes it special as it is now.
