Yes.

But the much safer way is:
Backup, make a new filesystem on the previous backing-device & Restore 
from backup.


The unsafe(!) 'inplace' method (that as an advantage doesn't need 
additional storage):
Just open the container normally, 'dd' the mapped container over the 
backing device and pray that process isn't interruped. Because it will 
be a huge PITA if it gets interruped.


But don't risk it, Backup & Restore is the way this should be done.
