Agree with the Baron here. Chinook is generally used for bittering, at which it is very good. Cascade and Simcoe sounds like the way to go. Good way of pimping up a kit.
You already have, in Chinook. Simcoe, Cascade and Chinook are three of the six hops Brewdog dryhop Punk with. Countless other breweries such as Kernel have successfully used that combination.
