Ambiophonics

Hey...
I've just read about 'Ambiophonics' technique. It is a method of expanding the stereo field of two short distant speakers, so stereo angle is 'too' small.
In a nutshell:
In an ideal setup, left ear will recieve only left channel of a stereo system in a room and right ear will receive only right channel.
However, in a real situation, left ear receives right channel information and vice versa.
This 'cross' information reaches the 'wrong' ear with some EQ (due to the skull filtering the signal), short latency and a lower SPL.
So, using this knowledge, one can 'inject' left side information into right channel, phase reverse it, attenuate, filter and delay for cancelling the 'cross information' (?!) and vice versa (right into left).
One can then create a feedback loop so that this cancelling process is endless.
Before I jump into experiments, let me ask if someone in this forum is experienced with this topic? Sounds an interesting topic to play around with.
