What did you hope to achieve, a 3D view or something else?
I toyed with this idea a bit as a possible way to image the ISS - say with the ToUcam on one EP using Afocal projection and use the other EP for guiding, and possibly a strategically supported monopod to steady the shakes. I did start playing with this, and struck problems setting up the afocal projection and camera mount and haven't got back to it since...
For 3D viewing/images I'm sure it could be done with a bit of fiddling. I met a guy back in 1993 when we were teaching the crew at the Parkes Radio Telescope some vertical rescue stuff on the dish. This guy's hobby was 3D images. He had two SLR's set up on a rack. He would take the same shot on each camera to produce two slides of the same subject from slightly different view points. He then displayed the images from two projectors set the same distance apart. I can't remember if he did anything with filters on the projectors/cameras to make it work with 3D glasses, or whether that wasn't necessary - I have a feeling that wasn't necessary
but I'm a bit vague on the details now...
I doubt the spacing of binocular objectives would be wide enough to give a 3D effect on an astro image though
... I don't think there would be any other advantage in using the different oculars...
