You can PM Jeff here, but Jeff is now with DAR. Jeff also does not have a modular setup to do any module modification, to the best of my knowledge. I bought his last 'Scorch' module in non-working order because he didn't have a rig to test it on. Pretty simple fix and I have the last one. Good luck, I hope this helps.
EDITED: I could point you in a couple directions if you were looking for specific module modifications. There are quite a few guys out there doing what you're looking for, if you haven't found them already. Feel free to PM to dicuss. You might also want to look on the MTS forum, it is much more dedicated to the modular line. http://mtsforum.grailtone.com/
