Here is the first recipe I came up with based on the ingredients listed on Goose Island's web site. I assumed that the malts listed were listed in order of amounts used, which may or may not be accurate, but it seemed to make sense: "2-Row, Munich, Chocolate, Caramel, Roast Barley, Debittered Black".
I took some liberties using a different bittering hop (summit). These hops were a little old, so that is why my IBUs look higher than the 60 IBU stated on the web site. I also did not have any debittered black barley at the time to I just used 2 oz of black barley, but I highly doubt that made much of a difference - such a small amount in such a huge beer.
I think this recipe is a little light on the darker malts, so the next time I made it, I bumped those up. I can post that recipe next.

Mash In Add 28.28 qt of water at 160.2 F 146.0 F 75 min
Notes:
Aged for 3 weeks on 1oz Maker's Mark soaked american oak chips.
Pitched on a US-05 yeast cake from a ~1.050 pale ale.
The taste is not as chocolate sweet as real BCS, but it does have a great bourbon/oak flavor.
I always make another beer out of the second and third runnings of a beer this big. I usually cap the mash with a little more chocolate malt and some crystal to add back what seems to disappear after the first runnings are gone.
