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.
Why not? It should, if that's the correct thing to do in that particular recovery situation

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.
In which case the FD would be in error, which would suggest that the FD was improperly designed, engineered, or programmed.

My argument is that if you, or I, or Wolfgang Langewiesche, or your average CFI is capable of writing down in words what to do in a given recovery situation, then a FD can be programmed to recommend exactly that.
