I like your build. I wish you had posted it a few months ago when I was trying to do my side by side conversion. Mine is very similar with a few exceptions: 1) put my taps through the side, not the door. I have a pillar next to the door that protects the taps from view/accidental knockage and I could fit up to 5 taps if i go to the 2.5 gallon torpedo stackers 2) My 10# CO2 tank is outside, attached to a 4 body secondary bank that I hung off a shelf w/ an old coat hanger 3) Used some PVC pipe cut down to fridge width as spacers so I can tighten my shank nuts to it w/o flexing the fridge wall (also put a layer of caulk between the insulation and the spacers) Going to attach my drip tray w/ super strong magnets, just want to avoid putting more holes in the fridge than I need to.
