Why can't the university add temporary bleachers in the corners of every concourse at Beaver Stadium?

I would imagine this could create anywhere from 1,000 to 2,000 extra seats, thus providing more room for those who did not already receive tickets.

It doesn't seem like it should be that big of a deal. Even if they could do it just for the Michigan game, they could get enough students into the game to break Michigan's single game attendance record. That gives them a little over three months to get it accomplished.
