Basic idea looks fine, but the system is also very important. There are 14 weeks in every season, what is your idea? Now the system is:Week 1 - scrimmageWeeks 2 to 8 - group stageWeeks 9 to 13 - second group stageWeek 14 - semifinal (friday) and final (monday)How would you change it to be able to compete 24 teams in second phase?
