I did it this exact way when I bought a new HDD for my laptop last Christmas, 
because then I could still use my normal system instead of booting a LiveCD 
and waiting for the sync to finish (which could take half an hour). Copying 
16GB from a laptop HDD to another one via USB is not that fast. Only before 
everything was done and I was ready to boot with the new HDD, I did another 
rsync with logged-out users on TTY1, which takes but a minute. IIRC I didn’t 
even boot a live CD.

And even IF there were some flaws in the mirrored system, there’d be no harm 
done as I have the original still around to amend them.
