You could just have 4 alliances of 4 teams but only 3 teams would play each match. This would resolve the issues of having 6 alliances and with only 4 alliances you could also up the number of matches to win from 2 to 3. This would give teams more potential matches to play. And it would likely take close to the same amount of time as an 8 alliance elimination bracket
