I vote no for several reasons...
The pedals are too close together already for my big feet. I have no problem heel and toeing now. Add on pedal features are just something to some loose and get in the way...I know a guy who's "goofy foot" pedal came loose, stuck under the carpet edge and stuck open, blowing a very expensive freshly rebuilt engine /ubbthreads/images/graemlins/crazyeyes.gif
Finally, I already have one car that has a tendency to trap my feet between the top of the gas pedal and the bottom of the brake, requiring more acceleration to what is already half throtled car in order to slip my foot out from under the brake pedal. Very disconcerting when it happens! /ubbthreads/images/graemlins/shocked.gif
All that being said, perhaps another style of Heel/Toe will be easier for you to master. I was taught (because of my duck-stance legs) to use my heel on the brake and toe on the gas pedal...this style works very well with my B /ubbthreads/images/graemlins/driving.gif
