So I'm very septic about your stopover, knowing that you also will have to go to LGA with a 30min ride with no traffic....
Best piece of advise I could give you is DO NOT MAKE INBOUND STOPOVERS unless you have 5 or 6 hours of layout. But as you are looking for TP, if you reeaaaaly want to do this particular itinerary, you better be the first out of the plane on arrival to JFK !
