its probably easier and may work out better if you buy one radio and try to move the right stick to the left even if upside down, if it works then buy another radio. the rest is just rev/nor throw, trims and servo horn placement. ive never seen one with two stick centering, but im not an aerial guy

id just try and use the right stick for driving a bobcat, unless its an articulated loader. check out channel mixing if the radio has it. use a toggle for high or idle, and the left stick for the loader bucket.
