I'm sure if you entered it in beersmith and scaled it, you'd have your recipe. I did just that and here is what I came up with. I subbed Zeus for the Alchemy blend, and this is at 62% efficiency since I normally only get around 70% and this is a bigger beer.
16 lbs 10 oz 2-row
2 lbs 3.5 oz Crystal 60L
1 lb 5.3 oz Special Roast (is this the same as roast malt?)
1 lb 1.7 oz Chocolate Malt
7.1 oz Midnight Wheat
1 Oz Zeus (boil 90 min)
.71 Oz Cascade (0 min, steep)
.71 Oz Willamette (0 min, steep)
.35 Oz Zeus (0 min, steep)
