Just bend it. I bent my Steamroller fork so far back that I had three inches of downtube overlap (yeah). The guys at the shop put the steerer in a fixed piece of larger piping and just moved it back to where it was supposed to be. I've been riding it with no issues since it happened last summer. I'm buying a new fork soon though, as the geometry isn't exactly what it was and I still have a little too much overlap. So if you're content with pretty close, go right ahead and you'll be fine.
