Custom crankshaft

Has anyone tried to modify a VNX/VLB type crank? What I mean is to reposition the con-rod across the crank to create a different size stroke. I need 54.5 mm and Ive got 57, so I thought maybe a machinist could pull the web apart, weld and bore a new hole 1.25mm closer into the crank and then reassemble. Has anyone done this before? Is there an easier way to shorten my stroke? Ive considered raising the deck surface the necessary 2.5mm, but I think this might become a problem with timing, especially around 10,000 rpm.
