I have no idea.
But I had to email RJ about something else recently, and got a very quick reply from the "Reservations Supervisor" at RJ office in New York.
It may be worth asking her if they would set up an RTW itinerary, and create an RJ record locator for ticketing either by RJ in Amman, or a Jordanian travel agent (if you can find one) or in Canada, if you can find a TA who can ticket on RJ stock? Gala Travels?

I was lucky: I booked an ex-KRT DONE4 at the end of September (to start in Dec), and a few days later, an AONE3 to start at the end of the DONE4.

Happy Travels.
