I have also been doing something similar to this - though I put the bad 
block handling into Squashfs (another RO compressed filesystem).  It 
therefore seems as if all the possible approaches have been tried: 
putting the bad block code in the NAND layer; implementing a new RO 
block-driver; and putting the bad block code in the RO filesystem!  It 
definately seems as if there is a requirement for this in the main source.

Pantelis have you looked at Squashfs?  This filesystem gives much better 
compression than CRAMFS.
