That's a very good idea.
It doesn't necessarily have to be the plane actually shaking. The vibrations of gunfire isn't you or the plane shaking - it's a neat way of depicting such sensation by shaking the 'camera'.
When a flak shell lands close(like those occasions when you hear a hit on your plane, but not damaged) the camera could vibrate to simulate the effect.
This would also be great with GVs - when you run into a tree or an object, when a shell lands on your tank, when bombs land nearby etc etc.. i
