Drinking & Pro:
Pro, good question, but I actually did something similar with my bar.
Here’s my suggestion, for what it’s worth.
Use the Straight Kegger bar plan, but leave out the keg box.
Then, using the same (similar) framing method as the bar, add the 4 foot section against the wall.
What I did is build my keg box in that 4 foot section (although mine is about 3 foot ) and build it as a keg box, see the builder’s gallery:

Be sure you make the 4 foot section deep enough to kit the keg and the insulation. A keg requires a minimum of 18″ width, 19″ is better, 20″ is too much. The black rubber coated kegs will fit 19″.
I’m not saying you HAVE to build the keg box, and mine took some time before I got around to completing it, probably a good year.
The other advantage to your plans is the the fridge can be placed behind the wall, with the front flush with the bar side of the wall. This makes for a more quiet (silent actually) keg box.
There is a section in the builder’s gallery that shows my bar in the building stages. http://www.barplans.info/gallery/thumbnails.php?album=5&page=1
