3D stereo sound with 4 speakers + room correction

Hi all,
I´m Johnny - a long time reader of Audiogon, hifi geek and music producer from Denmark - and I have a "different" question to all of you Audiogoner´s out there.
Have anyone tried to do a stereo system - but with 4 speakers and room correction + time alignment? Fx 4 (same) speakers to 4 monoblocks or 2 power amps from a preamp + room correction. Maybe you´ve just tried with 4 speakers and no room correction - anyways - let me hear your experiences.
I´m thinking of - sometime in the future - if funds and space allows it - to do a system like that. I would put 2 speakers as fronts and 2 speakers as side speakers. I imagine that the room correction and time alignment would make it possible to achieve a 3D stereo sound that reaches your sweetspot at the same time - but still in stereo. The sound stage would be almost all around you and massive.
Is this completely nonsense or would it make sense to do a system like this?
Ps. If I had the money - I´m thinking - Soundlab U1 speakers + 2 or 4 JL Audio f113 subwoofers and some great amplification + source. We don´t have Soundlab speakers here in Denmark so I have yet to discover the sound of them - though I have heard both the biggest Magnepans and Martin Logans - and several other high end speakers incl. MBL (the big ones) Adam (reference setup) Avantgarde (the big system). My own speaker are Audio Physic Scorpio - and I´m actually very pleased with them and I will keep them for a while.
Please let me know your thoughts on my question.
ps. and thanks for letting me dream away in the member systems pages :-)

I'm using quite a high-end four speaker arrangement at the moment, with no room correction and frankly the sound is pretty amazing (fuller, richer and more 'scary' good than with just the two channels).

Speakeers in front are Audio Physic Avanti III, rears are German Physiks HRS-120; I have them at the rear because they are omni-directional and so are easier to place and seem better able to produce that ambience. I'm likely selling the German Physiks as I had felt I only need one pair of speakers and they seem a bit of an extravagence having speakers costing over $30k for rears ;-) But, I'm loving the experience. When I do a/b comparison, it's just so much better with the four speakers. I think the key is having omni directional at the rear which fit in and disappear much better, even without room correction. My 2-cents; maybe it's not supposed to sound better, but believe me, it does.
