I would hope they would allow you to battle bosses and such... that would be awesome. Perhaps you could even place bets and stuff. Maybe you could even pit two monsters against each other and have them fight it out? That would be sweet! And yes, I understand what youre saying with the whole 'see the other person as a monster' thing. Only, the monster would need to have a similar moveset as Link. Maybe you would just see your player opponent as Dark Link?... Or, perhaps, you could choose your monster...
