Duh, that makes sense! For some reason, I was trying to think about it the other way around. One concern that I would have with multi-channel audio, though, would be the L/R not matching up with the center (and to a lesser extent, the surrounds). I suppose if the 2-channel pre had a dedicated pass through that didn't add much, then it shouldn't be too noticeable, though.
Thanks, Tom.
