Here is a clone I have drawn up but not tried. I think it will be close, but can't say for certain. The IBUs are right around 100, the alcohol is almost 11%. I would mash low, at no more then 146 degrees. All that alcohol is going to make this sweet and so you want it to finish as dry as you can, so pitch a HUGE slurry of a good, clean ale yeast. All the specialty grains and all that 120L Crystal are going to balance each other out, but still have a caramel tone that will fill it out. It will be dark as coal.
Enough. Here it is:
