And a passenger of size can quickly pass through exit, or are you suggesting they should not use overwing exits in case of an emergency?
The type III overwing exit is 20 inches wide. So yes, with a seat belt extender need, the likelihood of being able to quickly open and exit is greatly reduced.
It would be even harder on the a320 overwing as that requires someone to maneuver the door after removal prior to exiting.
