Shifters normal, no reason to change that and it'd be pretty damn pricey. All my bikes are rigged "moto" with the front brake on the right. Makes sense from every standpoint except some ancient and fairly silly rules related to using hand signals in traffic. The idea was that with your left hand off the bar to signal a turn you might need to slow down and would skid down or go over the bars using just the front brake. British bikes "reverse" the levers for the same reason.
