well, i bet that would be good to, but i guess my point was that with 3 lbs wheat and 3 lbs munich, you're only at about 25% actual wheat (dunkelweizens are usually up closer to 50).
like i said, i don't think it'd be a problem, with 25 percent wheat and a good hefe yeast i think it'd be great. you could partial mash some wheat malt to bring the balance back towards the wheat side of things, if you wanted. some specialty grains could be nice too, but if you do add chocolate i'd go easy on it. i've found the banana esters to clash with a lot of roastiness in past beers.
