I highly doubt it would be a waste of your time. On an educated hunch when you restore a nandroid all CWM does is format the partitions then load the data from the nandroid to those partitions; back to square 1 with old data being left behind.
Now, back to snooping in some O2x zips so I can port this to the O2x.
Edit: adding this to the Q and A.
