Feel free to improve upon this script. To use it, just chuck it into the X Rebirth directory (the one that contains all of the .cat and .dat files), and run it. It will create a new directory called 'out', which will contain all of the extracted assets in their original directory structure.
This should give modders some nice data to play around with
