Well there's nothing to stop anyone from making their own take on the battle, and as SS2Link said, two different results are fine provided the other has a reasonable argument to it and isn't brought about so that their preferred character wins.

As for separate pages, only battle royales have to worry about that, since those could have many variations on their rosters.
