Could you use your imagination for a moment, rather than try to find a solution to one extremely rare accident??
On the one hand... we know nothing really about what brought AF447 down, but the G-forces at 40,000ft plus at the top of a thunderstorm can be enough to start a break-up of an aircraft. Do you want to eject the FDR at that moment, before the rest of the sequence? No, obviously not.
On the other extreme, you ditch relatively cleanly, then the aircraft sinks. What G-force are you going to select as a trigger?
If there was a "simple" solution it would long since have been implemented.
