Brent, I've done this before a lot, it's a great workflow. Just stack exec and the world works as you would hope. As an example I have instructions for compiling GHC here, http://neilmitchell.blogspot.co.uk/2016/03/compiling-ghc-on-windows.html - only at the end is the fact I'm using a haskell package even mentioned.
