Dave has the right idea. KneeSavers are a much better way to increase Q, since slapping on a longer spindle than spec'ed for a particular crank will negatively impact chainline.
A riding buddy of mine uses KneeSavers -- they seem to work fine and have helped him eliminate some knee pain. At 6'4" and over 350 pounds, he's a good stress test of these things and they've held up fine.

Actually, this is for a Battle Mountain Streamliner. The bottom bracket will be just above the front wheel. The wheel can only turn as far as the spindle is wide. If we move the bottom bracket up, then the feet will come into play and then the knee savers will be ok.
