I would like to see an arena-like mode, maybe in a colossuem. 2-4 players compete in gladitorial bouts against the game's enemies. A crowd would be cheering and booing along. An emporer decides at the end with a thumbs up or down who won or lost.
Or I could go for an opposite mode. You and a number of players pick evil minion types to fight a computer or human controlled Kratos. You need to defeat him in a time limit and can respawn as needed but everytime Kratos kills someone, you'll drop regeneration and magic regeneration for him to soak up. It's similiar to the mode in Pacman Championship Edition when you get to be the ghosts. That would be my preferred online mode because it wouldn't disrupt what God of War is about. It would just put humans in the roles usually set out for the AI.
One other I can think of is a rail shooting competition on Pegasus. Characters converge on one screen and must try and take out enemies for points. You can bump eachother away but cannot harm eachother, and must fight for kills to score the highest points.
The last mode, which sounds a bit boring, would be a button tapping competition, like a competition quicktime event, and the on screen stuff would be some strong man competition stuff.
