I think that http://jsoftware.com/pipermail/programming/2013-January/031131.html provides the orderly approach you need here. You just need to reverse the order of the expressions Dan gives (and, perhaps, fill in a few blanks?). Anyways, you can use the same intermediate forms, going from ic to ic2 and going from ic2 to ic.
