If I was a writer for WWE...

I've always envisioned a Wrestlemania main event being a triple threat match between 2 great up-and-coming wrestlers such as Evan Bourne, Kofi Kingston, Byran Danielson, or even Shelton Benjamin facing off against the Royal Rumble winner being a face who has never won a world championship and the also against the champion. So it would be the Royal Rumble winner (face), the Money in the Bank winner from the previous year (face), and the champion (could work as a face or heel) in an elimination 3-way matchup.

Now, the way this would work out is the RR winner putting the champ in the finisher and the MITB winner pinning him thus eliminating the champion leaving two rising upstarts who have never won the championship to win. Once the champ is pinned and eliminated, I can guarantee the crowd would go wild knowing that history will be made for one of these two great up-and-coming superstars. This would be a dream of a Wrestlemania moment just like Shawn Michaels had after beating Bret Hart after the IronMan match.

Finally, the RR winner will put his finisher again but against the MITB winner who stole his pin on the champ and the RR winner will get revenge by, this time, pinning him and then winning the WWE Championship. Of course, the MITB will have to be slightly more popular than the RR winner, but not by that much. I see this as the perfect way to solidify the age of tomorrow's stars. Personally, I would love to see this work out with John Cena (Champ) vs. Kofi Kingston (MITB winner) vs. Bryan Danielson (RR winner)

All in all, this match would have hints of intense, emotional drama for the Champ who has a reputation to protect and feels he cannot possibly lose to these rookies. There would a sense of tragedy for the MITB winner who waited nearly a year to get the perfect opportunity only to lose it to the winner of the Royal Rumble winner who would feel an exciting joy through his veins once he wins the championship. And throughout the match, the fans would feel excited and on the edge of their feet thinking that something different and historic is about to occur.
