If you don't want a restart, just sit at home and win on turn 117. At least the other guild will have time to set up a counter-strategy if they gave one side an advantage from the start, while the others are left with nothing and essentially no chance to win the match without a restart.
However, the duration of the match is a rather sensitive criterion for player interest, much more important than the balance of the game.
If you want balance, you need to create a mirror map for 2v2.
