Will it be changed on stage my a pedal? Does he have a pedal that sends MIDI signal. If the answer to both of those is yes it should be easy. I haven't used Axe FX but I am sure it can do it if Pod Farm and Guitar Rig can. I'm sure there are even axe-fx pedal boards out there that will make it even easier.
