stop grasping at straws. Check in and immigration have to be done somewhere. If NYC-ORK is to beat SNN it must be nonstop. ORK to somewhere SNN does not serve might work in a one-stop.
The point about needing transport is of course well taken - however if you don't live in Cork city (say Mallow, Charleville, Mitchelstown) you will probably end up with the same problem for either airport.
