Player vs Player mod (esport 1v1 tournaments... Fifa, nhl etc)

Hello, would it be possible to add a mode for 1v1 tournaments? For example, if I had a tournament in NHL 23 and players were playing against each other... So that it would be possible to put players instead of teams in the league and playoffs? And so that achievements (trophies, positions, etc.) can be recorded in the player's card. Thank you in advance for your answer.
