That setup sounds preferable from my perspective, but if you want greater flexibility there is another alternative.
I am goingtoassume that the secondary regulators in your cooleraresimilarin design to the ones manufactured by Cornelius/Taprite/Micromatic etc being that there is a guage dialon thew top, a shutoff valve or barb on the bottom at the outlet, and 2 barbs on the sides,or a barb and a plug, which are the regulator high side,or inlets.
if you drill the second hole in your fridge and run your stout gas line into the fridge...
replace the barbs/plug in the sides of the last secondary regulator with gas cocks. connect CO2 to one side,and stout gas to the other. Open the gas cock for the blend that you want to use for the product that you have connected (and close the other gas cock naturally)
