There are even more solutions to this problem:
One is to convert the L/R Stereo image to Mid/Side do the volume control and then convert it back to L/R. This way any mismatch of the potentiometer would translate into a change in stereo width instead of shifting the image around.
Another solution would be to use one pot as a voltage divider, buffer that voltage and use the resulting current to drive two Blackmer VCA ICs (e.g. THAT2181).
