Lower the clutch pedal? I had to go to the garage to look. I have heard of owners whating to raise the pedal (adding a block to the pedal, wearing heavier shoes perhaps), but never to lower it. You might have to move the entire clutch master cylinder forward so as to create distance from the vehicle fire wall to then enhance the distance away from you. I have never seen this done, but suspect that it could be accomplished.
The other approach (less involved) would be to have the pedal reshaped. This might be accomplished by reshaping the attack of the area above the pedal to move it away from you. I am surprised that I am taking all of this seriously, but yes, I suspect it could be done.
