I dont have a dog in the K4 thing except that if they do come along then there may be a chance that I could fudge an I3 or I4 out of it. Oh and it would not take much to hack a driver off of a K4 and get a nice Atlantic out of it. But reality is there is no way I am purchasing a new (and probably expensive) to butcher the heck out of it. Hopefully the FEF arrival will drive down the GS4 prices on the bay and I might try and tear one of those up some day. I am getting comfortable with a razor saw....
