Definitely keeping it simple.
At 7% the C60 has a caramel sweetness which will come through strong, I think, although the US-05 yeast will attenuate more than the English yeast I used in my IIPA which will dry it out more balancing toward the hops. You could use less crystal with a dark crystal like 90 which would make me more comfortable you won't overwhelm the hop character.
Mash temp is good for the yeast IMO. Hop bill will be excellent. I'd brew this with confidence it'd be a good beer as is.
