Speak to Airbus Flight Test Dept...they have done a lot of stuff on this.Most interesting was the max braking rejected take offs.No pilot could beat the max aircraft auto braking...interestingly from your point of view the left brain stronger pilots started to reduce pressure on the left foot earlier (if I remeber they suggested weaker right brain controlled left foot)...anyway they have got all the info..speak to them.
I am left handed for writing only...everything else done with right hand.No problems apart from writing as indicated.
