#3 The Million Dollar Championship
The Million Dollar Championship began as part of Ted DiBiase's gimmick, but the title could be so much more. Instead of someone holding an unsanctioned belt, it could be used as a prize.
WWE has had great success with tournaments like the Cruiserweight Classic and The United Kingdom Championship Tournament, and it looks like a trend we will see continue.
The company could hold a yearly tournament with a kayfabe million-dollar prize in the form of the Million Dollar Championship. The winner could carry it with them until it's time to crown a new champion the following year. It would be more like the King of the Ring than a regular title.
Ted DiBiase could even be brought in to present the winner of the tournament with the title in a special ceremony. WWE has a beautiful belt just sitting in storage. It may as well be used to put someone over instead of sitting there collecting dust
