#4 The Shield
Roster change or not, this one would be a perfect main event for Survivor Series. Of course, it would be changed from 5-on-5 elimination to 3-on-3, but that's not the point.
WWE has teased us with The Shield officially re-forming in the past, and I wouldn't be surprised to see them do it again by the time Survivor Series rolls around. Regardless of plans for Dean Ambrose to return as a heel, this one has money written all over it. It was even teased in a backstage segment at one point on RAW, and the ovation from the crowd was ridiculously loud.

So here's how it goes...
The Shield dominates everyone they come across - that is until they run into the Balor Club. The two teams could go back and forth for weeks with singles and standard tag matches, trading victories in the process. Come Survivor Series, the two teams meet in a dream match in the main event (this would also help solidify Finn Balor as the main event player)
Win or lose, both teams would surely get a standing ovation (except Reigns because the WWE Universe hates him for some reason). A loss wouldn't hurt either group as far as fan recognition goes, and after Survivor Series they could cleanly move on to another story.
We've already recently seen Finn and Seth face off in singles action, and I for one was not disappointed. Similar styles compliment each other, and that would certainly be the case for all six of these men.
