AEL and AFl buttons on X-Pro 2?

For those of you with X-Pro 2, can the AEL and AFL buttons functions be swapped? It seems to me that the AEL button's location would be much easier to use "camera to face" by feel for locking focus (or back button focus) than the default locatoin of the AFL button on the side of the grip.

Thanks in advance for info, insight, observations.
