You'd have to have images that were rendered differently for left and right eye in order to get the desired effect.
I'm rather skeptical about the possibility of adding generic support in the emulator to provide 3D effects using red/blue glasses either. Again, the images need to be rendered differently for the left and right eye to get the effect you want, and I can't see how the emulator could intelligently make the necessary adjustments to the image. Of course you could always write new code that did so, but getting the old games to run in 3D without rewriting them isn't at all likely.
Separating the red and blue/green by a certain distance should work "sufficiently". But that's the most the emulator could do, because in games with 3D, there's not going to be a unified method of displaying that 3D.
