Other than the lactose, it sounds pretty good to me. I love those hops you chose, and I think the combo would work great together. (Maybe with a bit of Mosaic too??)
I did a 'milkshake' IPA with lactose (just 5 oz in a 3 gallon batch), and while it was a very nice beer, it would've been so much better without the lactose. (I also used Verdant on that one.) I'm glad I tried it, because now I know. In the future, I may put an ounce of lactose in an in imperial milk stout, but honestly I don't think lactose belongs in beer for the most part.
I mean, cheesecake is amazing. And eating cheesecake with beer is awesome too. That said..... I'm thinking naw. But do what you gotta do, what's best for me isn't right for you. I admire experimentation. Let us know one way or the other.
