I wonder how easy it might be to gently bend the shift lever shaft on an exhaust pipe bender? I shouldn't take a lot to bend it a few degrees and the radius could be selected from the stock bend radius blocks for different size pipes. Just a small bend would give you an inch or two difference in the knob position and greatly increase your comfort from a shortened reach. We used to do this with 356B shift levers which were much thicker than a stock VW shift lever - more like a Berg shifter shaft and bending the 356B version was easy. Just take it slow and try it a few times until it feels right.
