#4 Two of the wrestlers pin the third
As evident from this photo above, it could easily come down to two of the wrestlers pinning the third. While I know this was a joke about the Janela/Enzo Amore fight that happened about a month ago, it still stands to reason that two could certainly team up on one.
They teased dissension after they lost their match at Fight For the Fallen and this match is a byproduct of that. In multi-wrestler matches, temporary alliances are usually formed, but they rarely lead to to people picking up the pin on the same guy.
One reason why this could work would be to set up a future singles match between the two who picked up the win. AEW is always announcing matches for its upcoming TV dates and it could easily be a reason to have this finish. It could also be a specialty match between the two daredevils and it would be something to grab viewers for a particular city.
