#1: Becky Lynch vs. Charlotte Flair

The on-going feud between Charlotte Flair, Becky Lynch and Ronda Rousey is set to culminate at WrestleMania 35 when the three women could potentially headline the show.
The only issue the WWE is facing right now, from a kayfabe perspective at least, is that Becky Lynch has been officially removed from the match.

The easiest solution to that issue, of course, is to set up some sort of match at Fastlane between Becky Lynch and Charlotte Flair.
The two women have incredible chemistry in the ring, and if booked correctly, the match could make both women look strong heading into Mania.
Having Ronda Rousey get involved in the finish could set up a nice three-way staredown to close the show and provide the WWE with their money shot for all of their promotional material in the final build to Mania as well.
