Rebuild the east stand with a smaller capacity but really steep like tynecastle, taking up a smaller footprint allowing for more exits at the back.
Rebuild the mainstand, again quite steep so keeping close to the pitch, the offices and whatever else you can pack into a stadium can stretch out to the pavement as long as it is on 'stilts' leaving the same room for the small carpark underneath. Sorted.
