I like it! I personally don't care for the strong "earthiness" of fuggles, but I like the grainbill and the amount of hops with the kolsch yeast.
The only thing I would consider changing is the late flavor addition of fuggles. Not only is it earthy (which many people do like!) but it's very "Englishy" too. That's fine, but with those German flavored malts, I'd be more inclined to go with a noble hop variety like hallertauer or tettnanger, or even saaz. Crystal hops would be really good for flavor in that recipe, too.
