I'm really not an expert on ZFS, but at least from my point to
handle such cases ZFS has to handle at least the following points
  - GUID   a new/different GUID has to be assigned
  - LUNs   ZFS has to be aware that device trees are different, if
    these are part of some kind of metadata stored on the pools/fs
  - FS     Have to be mounted somewhere else
It looks as this has not been implemented yet nor even tested.

For Desaster Recovery this looks as a usefull way if it would work ;-)

In my experience, we would not normally try to mount two different
copies of the same data at the same time on a single host.  To avoid
confusion, we would especially not want to do this if the data represents
two different points of time.  I would encourage you to stick with more
traditional, tried, and true disaster recovery methods.  Remember: disaster
recovery is almost entirely a process, not technology.
