Lol, no I didn't see that sorry..
Well, if having rear access is impossible, then you really can't do a fixed rail system like mine. Well, you could if you really knew what you were doing with these racks, but I'm not even going to attempt to tell you how, it wouldn't be a good recommendation.
Like I said, your best bet is to find a really good finish carpenter and tell him what sort of look you are going for, and get the rack ahead of time so he can have it there to work with. I'm sure they can get you pretty close.
