Did you make it? If so, how did it turn out? There’s lots going on there and it sounds interesting. I’ve only brewed about 40 gallons of (AG) dunkelwizen so I’m no expert on ingredients (and have so far kept my ingredients simple to get a feel/taste for them) but…
I’ve been thinking about putting some chocolate nibs in my go to dunkelweizen recipe
and maybe even adding some vanilla or cold-pressed coffee (I guess I’m kinda after a dunkelweizen with a hint of chocolate/coffee/vanilla), but of course most here would now argue that it is no longer a traditional dunkelweizen and should be called a dark wheat beer with flavorings… Meh!
My concern is that unless you know your ingredients really well, it might be a little difficult to figure out the culprit if the taste isn’t what you were expecting. My feeling is start simple and slowly tweak it over time… but again, I’m no expert on ingredients.
Post again with results, I’m curious.
