I'd say bump down the Crystal malts, my input would be 8 oz cara-pils and 8 oz Crystal 10L. Bump the Munich up to around 2 pounds or so, and adjust the base malt to compensate for that. Will it be within the guidelines for color? Probably not, but I really could care less about color for IIPAs. They're all about the hops anyways. And on that subject: I'd say up those late additions. To at least 1 oz for each addition from 20 to 5 min, I'd even look at adding at least another ounce of hops at knockout.
That's just what I would brew to my tastes, I like huge hop aromas and pretty dry IIPAs.
