Idea: create a controlled stereo signal by mounting two pickups, registering different oscillation directions?

I have had this idea in my head for some time, and was thinking that some of you might have tried it.

The basic idea is to have separate pickups A and B registering different oscillation directions, and then sending these two (different) to left/right or to clean/fuzzy amps.

Let's describe the oscillation toward the guitar as north/south, and parallell to the guitar body as east/west.

If you pick with a downstroke, the oscillation will be mainly SE/NW, and this will mostly go into pickup A. If you pick with an upstroke, the oscillation will be NE/SW, and will mostly go into pickup B.

Various manipulations like a soft (harmonics) touch on top of the string, or on the side, or a hammeron, or a glass slide, would induce various tone combinations in the two pickups.

Is this feasible? Has it been done? If done - why is it not common?

There should be various creative possibilities:

A/B are sent to left/right, but identical amp/effect/speaker chains

A/B are sent to separate effect chains, clean/fuzzy amps or other differences

A/B : one is used to modulate the other

(one technical issue: oscillations parallel to the fret and parallel to the bridge might easily be dampened away. This could be addressed by constructing a bridge where the mount for each string is perpendicular to the guitar body)
