#2 Have Vince McMahon interfere

Why not throw in an interference?
Seriously though, with how known Vince McMahon is for conning people, one would have to wonder why they wouldn't have had the chairman of the board involved throughout the entire storyline. In fact, his one-off appearance to take Lynch out of the title match a couple of months ago almost seems out of place and like it was part of a bigger plan.

Unfortunately for the WWE Universe, the company never followed up on the development, and interestingly enough, neither has McMahon been involved in the feud again. With that being said, why not pull out a huge swerve at the end of WrestleMania 35 and have him interfere with the historic match.
At least that way, Lynch's eventual win would look even bigger and it would also create a situation where McMahon would go up against Lynch in the future! Maybe not in a one on one capacity, but the company could certainly realign McMahon and Charlotte Flair, using that as the big money feud for the women's division in the coming months.
