I removed the pedal assembly and took out the two screws holding the spline'd pillow block. Rotated the splines slightly and reinserted the shaft into the block then reinstalled the screws. As you can see from the before and after photos, the angle between the arm and the pedal increased from around 88 to 97 degrees. With the pedal back in place, this tipped the upper edge back away from the carpet relative to where it sat originally. The pedal angle doesn't seem awkward when sitting in the driving position.

The end result of this geometry experiment is that I now have full throttle opening with no compromise at idle. I will say this though - the pedal action seems a bit lazy. I have to push thru more of an arc to get WOT than I expected. Time will tell if it turns out to be a drive-ability issue.
