You know something, I really don't like the format of the Survivor Series. I don't mind the Raw vs. SmackDown element, but I don't like the Champion vs. Champion aspect, actually make it the Survivor Series.
So, actually do the same thing as the 1990 Survivor Series, and have the main event being Raw vs SmackDown, where the survivors from other matches tacke place. That way, you can also have it with Mens and Women trophies. Not only that, you build a stronger, and less predictable story than "Well, it's 3-3... this will settle it" like it is every year. Instead, have it where Raw's team has Strowman, McIntyre, Ziggler, Rollins, Ambrose, and Lashley who all made it through, but SmackDown only has Styles, Bryan, and a midcarder like Big E.
With that set up, you can make Big E a bigger deal by taking out a couple of guys, you can further push the Strowman/McIntyre, Rollins/Ambrose and 'Lashley's a douche' storylines, so despite having more guys, the Raw team just can't get along, because they all hate each other.
Not only that, you don't need to force a Brock Lesnar appearance out of it either.
