Not really mate, there's only a few inches at best with bars. You could also buy another triple clamp. eg: The pro taper kit is slightly movable. Definitely loosen up those bar clamp bolts and lean your hangers forward first!
Worst case, look in the Garage section at the top of the page, there's a guy in there named Timmeh. Check his setup out, he was like 7ft! lol
