Yes. Just translate the feet per minute into knots and you will also see.
Descending 12000 feet per minute is approximately 120 knots
You can have with no wind a ground speed of 120 knots in a stalling situation.
In this case you would have a path angle of -45°. If the nose was pitched 0° you would have an angle of attack of 45° too.
This poses the obvious question : to get out of a stall, one has to reduce the angle of attack. To get a more upward flight path angle, one has to regain lift, so it has to be done after being out of the stall and after reducing the angle of attack.
So, you have to pitch down to the flight path angle to regain speed and lift.
The question becomes, can you recover a positive flight path angle without exceeding some structural speed limit or structural limit, if you pitched down to this kind of angle ?
I know an airbus rated test pilot, he answered that the airplane probably would have exceeded VMO/MMO but not so significantly because of exponential mach drag, preventing the airspeed from increasing too much and the airframe from breaking apart.
