Just some nonsense fantasy booking, especially after this week, but you could build to something pretty unique at Wrestlemania. Restart a little Paul Heyman/CM Punk thing for a couple weeks, then have Paul run him down as a hack, stealing all of his stuff from a Japanese star who made it on his own, while Punk to borrow someone elses schtick to get to where he is. Could even play it as Paul was the one who turned Punk on this Japanese star, and now that Punk has pissed him off, Kenta wants revenge, and Paul is facilitating that.
The kind of booking WWE would never do, but it would make for a cool spectacle at Mania, and if you're going to get a dude like that over, that's the crowd to do it in front of.
