In single elimination tournaments, many times the number of players that sign up isn't enough to start that tournament. For example, a single elimination tournament with 64 players, but only 39 sign up, will be deleted. So, why not create an option, when a person is created a new tournament, to allow that a single elimination tournament with 64 players, but only 39 sign up in time to deadline, can start with 32 players (the 32 first players to sign up)?

My idea is: single elimination tournament with 64 players (for example) and if the number of players isn't enough, will there be an option to allow start it with 32 first players to sign up or 16 players or 8 players or 4 players.

And of course, the creator will be free for active 32 players only or 32 and 16 players or all options or don't active anyone.

This way, we can have in same tournament:
Backgammon: 64 players
Hypergammon: 64 players
Chess: 32 players
Checkers: 16 players
etc.
