Would walking involve actually exiting the building? From the maps I've checked, looks like you can go to the 3rd floor of the main terminal building and just use moving walkways from D/E to J.
Only 1 of them has opted in to PreCheck via AA LT PLT status and even then it's a crapshoot to be selected. In fact, since they are on an international itinerary to PUJ, they wouldn't be eligible anyway since PreCheck only works on domestic itineraries.
If the flight departs at 12:10pm, then I guess they would have to be back at D/E security by 11am. That should give them some time at the GE interview office in J...
