The other item I can suggest on this endeavor is if you do not already have an Atomic 2nd stage for your back up is to buy a complete second regulator that is DIN. Cost wise it is a bit more but then you have second first stage which is can be nice to have along for extended trips.
I am possibly thinking of saving some more and just keep an eye out in the classified for a used B1 or Zx2 in DIN. I saw a B1 DIN for about $200. So may options, but I do like the way your thinking.
