Depending on the shape of the pedal end of a crank arm, it may be possible to shorten a crank set. The minimum amount you can cut off is around 22 mm. So if you can find a reasonably beefy 175 mm crank, you can make a perfectly good 153 out of it.
Cutting and tapping the arms is not rocket science, but it helps to have a spare set of steel crank arms to use as a guide so the new pedal threads are at the right angle.
