I feel like you have two ~½ partitions that you need to aggregate and 
try to access.  I half way expect that you need to image the drive, and 
then extract the two ½s and put them back together.

I don't know if losetup can ignore something in the middle or not.

I would then expect that your file system in the new spliced back 
together ""partition to be okay.

I /think/ that most modern file systems have addressing within the 
partition and not subject to physical location on the disk.  As such, 
you should be able to mount it fairly cleanly.  I would expect that 
files are no more corrupted than they were before the move.
