Switching the layout would definitely suit the Clockwise rotation most ROAR tracks stick to, but if someone has already grown accustomed to the inherent torquesteer on the factory layout, then switching the layout might only confuse them. It's definitely worth a shot if you're looking for something different, though.
Note, in the drawing, the dimensions are exactly as they are on the factory chassis. If you want to move the battery cells inward, you'll have to adjust the dimensions. Other geometry that is not on the drawing is the holes for the front and rear brackets. It might be best to assemble the chassis and drill the holes last, to align them properly with the brackets to avoid a tweak.
If someone wants to send me a spare Yokomo chassis, I can model it up, too.
