The thing that throws it into 34C as far as I'm concerned is the American hops. If it tastes like American hops at all, then it's not a true German hefeweizen base anymore, but rather an amalgamation of maybe three different styles!? I don't know if it's okay to say "German hefe with lemongrass AND American hops". Hops are probably not the herb or spice that 30A is looking for. And with a traditional German wheat beer yeast in there, it's not an American hefe either.
