Changing controller ports mid-game

[Brenmaster10]

Im playing a game called Dragon ball budokai tenkaichi 3 for the wii and me and my friend want to play tournament mode. the game obviously thinks that since we are using netplay that we are in the same room but thats obviously not the case. The tournament mode requires you to switch "controller one" "hypothetically" to one another. The game works perfectly but without being able to switch who controls which controller mid game this functionality is completely useless within the game. I would like to have the option to change who controls which controller mid game with a menu similar to golf mode or something like that.
