I dont know that 320s would sink at the old terminal but size might be a bit of a problem, infringing the height restriction from the center line. What was the biggest aircraft that parked on the old apron? I seem to recall a 737 parked there at one time, but I could be wrong. Also, I'm not so sure there is not as much parking as there is space at the far side, the loadbearing and condition is very poor in places.
