Yup, may be able to pay the change fee, with no fare difference if lucky, or even a lower fare resulting in reduced change fee or even discount.
Lastly OP may already have a long layover if ticket already booked. I'm not sure though, wording leans toward not yet booked in my opinion: "is a possible ticket"
