I bet that mentioned party deck on the south endzone would be included as part of a concourse overhaul and facade improvement of Bramlage, similar to the EZ at Clemson and the renovation of the Pit at New Mexico.
Clemson EZ:

The Pit
(old): (looks worse than Bramlage Exterior)

The Pit
(new) with new raised ceiling, ring of suites and exterior:


(But imagine the Clemson football suites on one end, obviously, and made with a more traditionally-designed limestone finish)
Doing this at once, since its the same building, only makes logistical sense.
