Well, there are some issues, I'm sure.

Ferinstance, if y'all had the same dither in both channels, and it correlated, y'all might get some false imaging cues if you were listening at a point where the dither was audible.

I suppose somebody's done that, but I hope not.

There are some experiments y'all could try. Take two independent white (or pink) noise sources, and mix them in different proportions of M (mid) and S (side), that is to say
L=M+S and R=M-S

And see what proportions give you different results.

Now, y'all have to recall that the cochlea is a frequency analyzer, so that's why the frequency domain matters, on the other hand, it's a short-term analyzer, with different time/frequency tradeoffs at different frequencies, so the old FFT isn't as handy as it might be.

There's quite a bit on this in Fletcher and Zwicker's books, but it's not so accessable, sometimes.
