No such thing as a 2 hp wide power supply module exists at this time. There are some that were out a while back, but you'll notice that the manufacturers discontinued them due to revisions that made these modules larger. There's also a concept module from Endorphin.es, but it's not in production...nor does it have an on/off switch, which is unadvisable.
Another issue with the Moog cases are module depths. These don't have an even depth to them across the entire backplane, so there could be issues with modules not fitting. And with many of the 2hp modules coming in at 42mm depth, that's cutting it close.
Just leave the M32 in its own case, where it has its own power supply (which many Eurorack modules cannot use, btw, as it only provides +12V) and where its housing is already bought and paid for. Not wanting to beat a dead horse here, but housing something that already HAS a housing in a Eurorack case isn't cost-effective nor a good use of space.
Lastly...using teensy-weensy modules all jammed together with very little clearance between them and really tiny controls is pretty difficult unless you have fingers the size of toothpicks. Not fun. You may want to reconsider this "jam cab full of 2hp modules" idea...
