#2 - Paige
This is probably a dream match for many wrestling fans and there is a pretty good reason for that. Not only have Paige and Asuka never crossed paths during their time in NXT(As Paige left NXT long before Asuka joined) but they also both utilise submission-based manoeuvres that would make for a great match.
Why Paige, though? Beyond this being a dream match for The WWE Universe, a win over Asuka on the main roster would be a great way to put Paige's career back on the right trajectory and establish her as one of the greatest female heel stars the company has ever laid eyes on. Also, don't forget that despite seeing her on TV for a while, Paige is just 25 years old!
Yes, it is risky in the same way that having Reigns defeat The Undertaker at WrestleMania 33 was, but it could pay massive dividends for both superstars if done the right way. In fact, WWE could probably have the two superstars trade victories and the title for months and it would be absolute must-see television, thanks to their intensity and in-ring ability.
