The student side is already pretty large, foot-print wise, and not very steep. I feel like any expansion (which I wouldn't predict happening any time soon!) wouldn't entail moving "out" so much as rebuilding it more vertically, or with a second level.
The student side is identical to the Tower side - at least as far as steepness and pitch of the stands. 100% identical.
The one difference is the student side has all the infrastructure (restrooms, concessions, storage, etc.) on the end farthest from the field. The same infrastructure is on the end closest to the field on the Tower side. Never been sure why that is - but it makes the student side seem bigger and less cramped, IMO.
