Last year, there was a report in the media (print or electronic) that Chris Hill had spent a fair amount of time sounding out other schools that had completed renovation/expansion projects.
The one on which he spent the most time was the OU Memorial Stadium. IIRC, OU moved its luxury suites from the 50-yard line to the end zone.
I’m guessing that’s what the UU will do. They’ll probably install luxury suites and put in about 3,000 - 4,000 extra seats.
