#1 Make it a lumberjack match with all the contestants they've beaten
This seems a bit unrealistic given that Samoa Joe has a United States title match and Randy Orton has a match against AJ Styles, but there's a remote possibility of it happening, especially given that there are absolutely no plans for the SmackDown Tag Team Championship.
There are multiple teams on the brand, but even so, The New Day, including Kofi Kingston, have gone through The Bar, technically went through The Usos and they could even have Samoa Joe and Randy Orton at ringside to make the match all the more dramatic.
This storyline hasn't just been about Kofi Kingston's WWE title pursuits, it's been about the locker room and their respect for Kingston as well. Though getting many superstars would undoubtedly be overbooking the match at its finest (and very unnecessary too), it wouldn't be surprising to see it become a lumberjack match.
