Not familiar with that specific fridge, but 4.4 cubic feet will probably hold two cornies as well as the CO2 tank.
I tried finding a pic of your fridge, and if the one I found is correct, you'll have to do some frightening work to get the kegs in there. There is a freezer compartment at the top, and this is probably where the cooling lines are. You'll have to bend that thing down and out of the way without kinking or cracking the colling line.
I have a 4.3 cubic foot GE mini-fridge that also had the freezer compartment. The kegs almost
fit under the freezer, but nto quite. Once you have the ball-lock connectors attached, it definitely won't fit without moving the freezer compartment.
