... relocate some students to "field seats" like at an NBA game. These would be temporary bleacher seats ringing the field on the track and at the same height as Row A (any lower and you cannot see over the heads of players on the sidelines). Think of it as Cameron Crazies but all around the field. The seats are put up for each game and taken down afterward.
It would improve the seating for students, not take away one premium seat from an alum, and increase the noise no matter where the line of scrimmage is. I have a feeling "The Wave" would be a bit more intimidating too!
Edit: And it would add thousands of additional seats to The Big House and likely do it relatively inexpensively.
