Match waveform pattern and apply it to another wave form?

If you can spread the mono track why bother mixing in a low quality stereo track?

True. I was concerned about it being to center heavy since the stereo track has a center portion as well. Unless if I extract the center portion from the stereo track. I will try it out and see how it sounds.

If you want a wider sound stage use more (increase the volume) of the stereo track and less (decrease the volume) of the mono track. But the tradeoff is that the audio quality will get more like the bad stereo track.

Your earlier idea of subtracting the right track from the mono track to produce a new left track, and vice versa, will suffer from the same sort of problems.

Why don't you send a small (time-aligned) clip of each? We could see what we could do...

Here are some samples of the same piece. One is in low quality stereo and the other is higher quality mono. Interested to hear what you come up with. Thanks.

This seems reminiscent of a previous thread of yours:

As I said there, removing the center portion of a stereo pair produces a MONO result, so that won't help you at all here.
