Entirely possible, although it is the turn coordinator not the artificial horizon that is primary -- to determine the direction of the spin. Nose-down elevator, rudder opposite the spin, the when spinning stops recover from the dive using airspeed & altimeter for pitch control & the turn coordinator for roll. Those instruments don't tumble.
I'm told that in the 1950s, spin recovery in simulated IMC was a requirement for some ratings (commercial, instrument, and/or ATP - not sure which). Not so much now, obviously, but with a suitable airplane and appropriate instruments, it is entirely possible.

In other words, after some training, is it possible to recovery a spin solely by relying on instruments?
If using a vacuum-pump traditional attitude indicator, I assume the answer is no, since there are limitations for its pitch and bank indication. What about an AHRS-based attitude indicator? Is it capable of matching 360° attitude changes in all directions, and catching up (without delay) with fast rolls? Can it filter out vibration well enough, so that a pilot is able to perform a spin recovery maneuver?
