#3 Becky Lynch challenges Stephanie McMahon for a match at WrestleMania; if she wins, she gets inserted to the Raw Women's Title Match

If you clearly remember, Daniel Bryan boycotted WWE with his Yes! Movement before WrestleMania 30 to demand his title opportunity.
He challenged Triple H to a match at the show of shows with the stipulation that if he won he would be inserted in the main event between Batista and Randy Orton making it a Triple Threat match for the WWE World Heavyweight Title.

WWE can do something similar with Becky Lynch. She can also boycott Raw demanding her fair title opportunity which was taken away from her.
Then, she can challenge Stephanie McMahon in a match at the WrestleMania which if she wins she gets inserted in the main event match between Rousey and Flair making it a Triple Threat for Raw Women's Title.
Both the stories won't be exactly similar as WWE could possibly try some other way for Lynch to challenge Stephanie instead of boycotting.
But this match should definitely happen, already it is a rumored match for this year's Summerslam pay-per-view doing it early at WWE's annual event with the current storyline would be a right decision by WWE.
