I don't see any real issues with the posted recipe. It may be a wheat beer but it only uses 40% wheat. My last batch was a weizenbock with 60% wheat that I milled pretty fine trying to push the limit on extraction. I set up for a very slow sparge, not in fear of a stuck runoff but for maximum extraction due to the high gravity I was attempting to reach. It paid off, exceeded my calculated gravity and no stuck runoff.
With that said, I would agree with drengel. Brewing ag for the first time, you are actually putting yourself and equipment through a test run and would only make sense to start simple, I would also add cheap. No matter how well or bad it goes, it will only gets better after that.
