Why not brew an altbier? Some of those are up to 60 IBUS and they do have some late additons. Very similar to what you have except uses an Alt yeast.
I think your recipe is fine however, b/c it sounds like you know what you are going for taste wise but I think the alt yeast would give you a more "german" character.
Kegged: Millenium Galaxy IPA, German Pilsner. Apricot Blonde Ale, ACE Witbier, ACE American Wheat.
