I don't know of any current technology that can do what you want. I assume you can't get a camera directly in front of your subject. I'd suggest getting one camera as close to center as you can, and go with that. Most books recommend shooting subject somewhat off center. With the right lighting (key light on the short side of the face, fill on the long), it looks more dimensional.
