It is a very difficult problem. But it is not NP-hard. Given good enough sensors and detailed enough information about speed and turn radios from the GPS, centripetal forces can be accounted for in the AHRS solution. Professional units does this already, but in this case professional means $$$$$ systems used in real drones. With real ring-laser gyros, there is so little drift that you hardly need any other sensors at all to keep a gimbal level. And hopefully our budget range of equipment will get there shortly.
