module-remap-source would be nice to have. But we don't have it.

A very ugly hack, which I'm not sure even works, would be to configure
the channel map of the sound card to have only aux channels (required to
prevent remixing), then load a null sink with two channels (channel map
matched to the desired channels on the sound card), then load
module-loopback that loops the sound card to the null sink. Then you can
record from the null sink's monitor.
