I would try:

1.  Shut down.  Disconnect your backup and home drives.  Install a new 
drive.

2.  Boot OS.  Set up partition, LUKS container, and file system on new 
drive.

3.  Shut down.  Connect your backup and home drives.

4.  Boot Knoppix live CD.  Open all LUKS containers.  Mount backup and 
home file systems read-only.  Mount new drive file system read-write. 
Copy backups and home data to new drive.

5.  Shutdown.  Disconnect backup and home drives.

6.  Boot new OS and verify new drive has backups and home data.
