From @AdamSven: Could you see a multi-man match a la MITB be a successful (quick fix) way to promote talent from NXT onto main roster?
That's an idea I really like. Put six or eight guys from NXT in a Money in the Bank style match and the guy that gets the contract gets a permanent spot on the main roster. To make it even better, they could say the winner gets a title shot at any title other than the WWE Title, so the guy that wins can go after the IC or US singles title or bring along a partner to go after the tag partners. A reason that WWE may not be willing to do that kind of thing is because they don't want NXT to be seen as an inferior brand where people win matches to get off the show. That's why I added the title match idea because then it's a reward for somebody that is considered "new" to the fans. If a guy like Adrian Neville or Sami Zayn were to win that then that would be perfect. It's these kinds of ideas that WWE has to do in order to make things fresh. They barely acknowledge NXT on their main shows even though they really should because it's an important part of the company that can be seen on WWE Network.
