The net result is going to be very much like an american style pale ale. American ale yeast is generally so clean that if you have a lot going on with hops and crystal malts, you might as well have used a lager yeast.
I've used lager yeast in an american IPA before, and it really didn't make a noticeable difference from US-05. Well, that's not true, I certainly noticed the additional effort involved in fermentation temperature control that's necessary for the lager yeast...
I agree with gray, you'll be missing out on one of the key components of a great bitter.
