4. Brock Lesnar
This one is a bit tricky now because Lesnar's a heel and has been since he returned to WWE two years ago. A face turn is possible, though. I think babyface Lesnar could happen after WrestleMania when he loses to Undertaker and Paul Heyman ends up ripping him in a promo for not getting the job done. Lesnar could go after him, but who makes the save? Batista. He could be a new Paul Heyman Guy and they would have a huge program they could do for SummerSlam or before it if Lesnar wants to work more often. There's a lot of history between them even if it's not something that has been on WWE TV. It's something that goes back to Ohio Valley Wrestling when they training in WWE developmental at a time when guys like John Cena and Randy Orton were there. If they were to incorporate that into promos, it would let fans know that these two have a rivalry going back 12-13 years instead of something that is new. A power match between one of the most athletic big guys in Lesnar and a hard hitter like Batista would work really well. There's also a MMA background for both guys although Lesnar's is deeper since he was a UFC Champion while Batista had only one match. Lesnar has the tools to bring out the best in Batista. The match seems like it's very possible even with Batista in the heel role.
