The Legend of Zelda: Four Swords Adventures actually has "split screen".
The TV-screen shows the room with the most players, and if a player wonders into another room, his GBA shows that room.
Of course this game won't have more screens available, but the concept still works.
The screen splits if the players are not in the same room and melts together again.
The last thing to consider is two players and screen ratio.
