Yes, /usr can be read-only. That's how my systems normally run.
I do see a problem with your "cp -a /usr /mnt" command. That's going
to create a directory /mnt/usr, and when you try to mount that
filesystem on /usr your original /usr directory tree will now be in
/usr/usr and that will break just about everything.
Try "cd /usr; cp -a . /mnt" instead.
