#2 Make Rousey versus Jax the main event

In all honesty, this match deserves to be the main event.
Not only is that evident by the polarizing reactions that Nia Jax is currently receiving after injuring Becky Lynch, but also by how much of a big fight feel this match up has to it. In fact, between Rousey's versatile move set, and Jax devastating offense, its one of those matches that highlight everything right with the women's division.
It also will leave the crowd absolutely on edge after what Ronda Rousey did to Charlotte and Becky Lynch, which will have them anticipating some kind of retaliation throughout the entire match. Maybe WWE could even have both of the women come back out all taped up and end things in a DQ that protects all women going forward.
In the end, it may not be the finish The WWE Universe wants, especially with how much they want Jax to fall at the hands of Rousey, but it also could be a crucial step in the build to WrestleMania 35.
