No, the 757 ceased to be produced because the commercial/marketing departments of major airlines,
SIA for one, back in about 1985, didn't like single aisle and the baggage loading system of the B757.
In Europe most A320 operators use containerized baggage. This would be an enhancement for a A322 over the 757.
I think in the US most airlines don't use them because the 737 and 757 don't have them either, and it saves weight..
Also the cabin would be wider and significantly more quiet then a 757.
Not unimportant for flight up to 8 hours.
