Improved shear/stall-spin alarms

I just wondering if current technology could provide improved stall-spin warnings/information.

For example, suppose you installed a pitot at each wingtip (and I'm making an assumption you need this level of resolution) and had an instrument that monitored/stored wingtip airspeed and fluctuations … and had inertial inputs that could provide information about how cleanly you were flying the ship.

This data would be evaluated relative to a flight envelope (algorithm and envelope would have to be developed)– and if you were near the envelope boundaries – because of atmospheric conditions (gusts or shear) … or how you were flying the ship (slipping or skidding) … or if you were close to the ground/terrain … alerts would display/sound. (Could this be a feature of our modern varios.)

Or do we consistently fly too close (or over) an envelope edge to allow this to work in practice.
