That's definitely not a black IPA. That's a ridiculously roasty imperial stout with a ****ton of hops. +1 for replacing roasted/choc malts with a dehusked/debittered roasted malt. If it were my recipe, I'd lose the black, roasted, and chocolate malts completely. Add .5-1lb of a dehusked caraffa or blackprinz malt. I'd also probably cut back on the c120 to .75lbs, but that's just my preference.
All of that roast is going to seriously take away from the hops, which should be very forward in a black IPA. I'd also cut back on the bittering hop additions. I'd move probably half of your 90-30min additions to somewhere between 30 and 0min.
