IDK our rec league does something similar when an age group has a lot of girls who tryout. But usually the first team will play a "B" schedule and the second team will play a "C" schedule. Assuming they have enough coaches. We don't do anything like "1st place manager runs the summer team"Especially if Team A is the #1-12 players and Team B is the #13-24 players.
Even my fantasy football league uses a snaking draft order!
