I was thinking something like that, except I'd swap the two images if I was doing side-by-side. With your setup I have to point my left eye to the left and my right eye to the right, which I've never been able to do except when the images are small enough that I can aim my eyes normally at a point near infinity. I find it much easier to cross my eyes at a point just in front of my eyes. It's tiring to hold that kind of gaze, but much easier for me to find and "lock" than to look "behind" the pictures.
