The important thing is not to pull back on the stick while the aircraft is still in a spiral. All this is ab-initio stuff.
A FD recovery (if it is invented) would not prioritize wings level first. It would presumably only display direction of turn required and direction of pitch up (aircraft in a spiral dive for example). The pilot could be sucked into simultaneously rolling and pulling top satisfy FD commands. Not a wise move.
Automatic leveling functions can already do that. Those are available for a few bucks in RC planes, and considerably more expensive in GA planes, for example with the Garmin autopilot "Level" function. Programming wise that is pretty easy to implement. To get it certified is of course a different thing altogether. See a demonstration of the Garmin retrofit AP.
