If I understand your situation correctly then you need indeed to rebuild
your intird so that it uses the correct root partition. (It may be
possible to simply edit the existing initrd to reflect the change, but I
would not know how to do that. You should keep a backup of the current
initrd in any case.)

How do you access your system at the moment? Can you boot from a rescue
CD and mount the encrypted root partition?
