Mike, you might have read something I commented on in the past, but you don't recall the point clearly enough. The problem with Y-connectors isn't going one into two(or more), it's going two into one. When you try to combine two voltage outputs into one input simply by using a Y, the dumb voltage doesn't know that it's supposed to go only into the connected input. Instead it also runs up the other branch of the Y into the other output, causing at least distortion, and possibly damage.
So yes, Mike; no one has ever done that before. Your success with the experiment will assure your undying fame in the annals of Axiom.
