Drilling a hole in a shifter reverse lever?

Here is a picture of my original factory Hurst shifter on the right and a Hurst Competition Plus shifter on the left. I installed an alignment pin to show where the path of a drilled hole would be through the reverse lever of the factory shifter. As you can see the Competition Plus shifter reverse is a little longer before the S bend when compared to the factory shifter. If it was drilled for an alignment hole, then a fair amount of material would be removed from the lever.
