Is it possible to make a Friday the 13th Game style matchmaking system?

In friday the 13th the game, theres a max amount of 8 players that can be in a lobby but the game can start with just 2 players.
Instead of joining a match thats currently in progress you can only start or join an existing lobby, once all the players in the lobby hit ready and theres 2 or more players in it an actual match starts.

Nobody can join in it, after it starts people can only disconnect from it. Once the match is won by either side or the killer / all the survivors disconnect, the match gets closed and youre put back into the main menu / post match screen which shows all the points you made in the game.
