Imperial Stout recipe

Ok, so I've never brewed an imperial stout before. I came up with this while daydreaming at work today. No idea if it's going to be any good or not...suggestions are welcome.

I'ld leave out the brown sugar.

OK, here's what I think I'm going to go with. I cranked up the Chocolate malt. I also adjusted the efficiency down since my setup seems to suck with bigger grain bills.

8 oz. of Black patent? I'd stick with the 4 oz. you originally planned.

I actually made a coffee stout this winter (OG about 1.070) with .5 lb of black patent - I didn't find it overly strong, but maybe that was the 20 oz of espresso covering it up?
