I am a bit late on this discussion but my input is based on practical experience flying in (severe) turbulence created by rotor acticity in mountains, mainly towing gliders.
The only way to not overload any airframe and flight control components is "to ride it out" until clear of the region of turbulence.
To fly in the wake of another (heavy JAL), as is the case with the AAL Airbus, is to be avoided but if turbulence is entered "ride it out". Passenger discomfort will result as the result of unusual 'g' loads and attitude changes but more than likely, no total losses.
I am assuming the aircraft is handflown and not on autopilot. (note the BAC111 loss over Georgia USA, quite some years ago)
