If you have other Solaris clients (or the NBU master server) still running 
then it can be really trivial to get a Solaris client back online.  And you
don't need BMR.

Take the new OS disk, stick it in a running machine that can take that drive
type.  Layout the partitions and the filesystems.  Restore the disk from
NBU to this alternate destination (renaming hard links, not renaming soft 
links).
Use 'installboot' to make it bootable.  Pull the drive, stick it in the proper
machine and boot.

This way there is no time spent with flash or jumpstart or CD/net booting.
You're limited to how fast you can restore the drive using NBU.
