This is exactly what we're looking to do. Do you know of any relevant areas in the Xen source code where this may be taking place?

Probably?

Your question isn't very detailed; you might benefit from reading this:

http://wiki.xenproject.org/wiki/Asking_Developer_Questions

Would the following algorithm work?
- pause VM
- copy data from gmfn A into temporary buffer
- copy data from gmfn B into gmfn A
- copy data from temporary buffer into gmfn B
- unpause VM
