#4 A RAW vs. SmackDown power couple mixed tag match
As it stands right now, Becky Lynch and Seth Rollins aren't the only power couple in the current roster. Charlotte Flair and Andrade are very much a couple too and could prove to be credible challengers for Lynch and Rollins. Imagine just how good a match between the four individuals could be.
Bear in mind that WWE could always do this match with Zelina Vega. However, Vega does not have the same kind of appeal that Flair does. Moreover, people would want to see two real-life couples slug it out and not a pairing that WWE has made up for the television product.
The promos leading up to this dream match could also become very 'real' and very personal. The ideal stage for a match like this could be Survivor Series provided Andrade becomes WWE Champion by then, and Charlotte Flair regains the SmackDown Women's Championship.
