| Just run the stereo mix up a pair of channels. Make sure you align them with tone.
This flies in the face of public opinion on the summing thing and it does require that your itb mix is technically good from a gain structure perpective. But what you find is that every part of the analogue summing advantage is there (width depth bottom end) except headroom increase which is why the itb box needs to be right.
Try it on one track both ways and making sure they're perfectly level matched, compare them. You might end up saving yourself some time.
