Reply to X session pro desoldering

Anyone done this? I'm still looking at building a controller with one of these and several other parts. My problem seems to be putting all the parts together in one unit without the enclosure being huge. The X session pro circuit board isn't large at all, but when I put it next to the other parts, it all becomes much too big. I would like to place the circuit board at the bottom of the controller and solder leads up to the mixer section of the S4 clone.

I was wondering if anyone has done this before or has any info on the units. Adding decent buttons won't be a problem, but are the pots/faders 10k? Are the pots /aders easily de-soldered etc?

Any help welcome. If no help appears, I may use this as a mini build log for the X session pro part of my larger project.
