Speed and aggression.

so that everyone can play and to avoid the Swiss system, could we switch to a group stage? In the Swiss system, everyone plays the same number of games, but losing 2-3 games significantly reduces their chances. However, in a double-elimination playoff, those who advance from the group of 4, for example, still have a chance to win after 4 games (assuming they lost 1 in the group and 1 in the upper bracket).
