Cut the crystal to 1 lb, the pilsner to 9.5, use an ounce of tradition and 1/2 oz hersbrucker at 60 minutes, a half ounce of hersbrucker at 30 or 45 minutes, and your choice of ale yeast, and you'd have a pretty nice, light to moderately hoppy (maybe 30-35 IBU) pale ale. Or, if you want to give a lager a try, the same grain bill would make a pretty good pilsner with, say, WY2278. I would only use a half pound or so of crystal though, max, and I would probably only use 9 lbs of pilsner malt. OR, use kölsch yeast with the same grain bill and brew a kölsch.
