You could move the ISS to a lower inclination orbit, but it would take an incredible amount of energy. A VASIMR type thruster could eventually move it to the desired orbit but that would likely take from months to years. There's a pretty good explaination here. A plane change from the ISS's current inclination of 51 degrees down to even 28 degrees would take several km/sec of delta-v. Since the ISS is so massive, you're talking about a lot of energy to move it that much, even if the energy is provided over a long period of time. It's actually more efficient to do the plane change in one maneuver than in a series of smaller ones, but that simply isn't practical for something as massive as the ISS.

Depending on the amount of propellant on board, a CEV might be able to go from a 28 degree inclination to a lower inclination, but it's unlikely they'd carry so much. It'd require a delta-v of over 3 km/sec. Depending on how they plan to recover the CEV (will it splash down in water or will it come down on land?), you might have to do another plane change to get back to your landing zone.
