No way. These are only going to be used for high yield routes. (With a high level of business class passengers, VIP's, and full fare paying coach class passengers.) DFW-Sao Paulo, DFW to London Heathrow, and later, New York JFK to Sao Paulo Brazil. are the scheduled routes for these premium birds. Where the money is.
Routes between North America and the Caribbean are notorious for being very low yielding routes, despite being full. (less higher fare paying traveler, less business class passengers, most passengers flexible with their plans and won't fly unless they get a deep discount fare-whether they are tourists visiting for leisure travel or immigrants going back to their country to visit friends and family) This is why only lower cost carriers (JetBlue, Spirit,) can have good size operations in the Caribbean and actually make a profit on those routes.
