Ghost 14 License ?

I'll give scenerio:  One system, three .5T disks.  Each disk holds it's own system (selected on boot-up), but each is also usable from each boot disk.  I want to "round robin" the images. 

disk0 snapshots to disk1 (when booted on disk0)

disk1 snapshots to disk2 (when booted on disk1)

disk2 snapshots to disk0 (when booted on disk2)

 

Can I do this on one license, since the software is only running on a single disk at any one time?

 

Thanks in advance
