1) You can (quite easily) use a hex editor (standard on most Linuxes) to edit the *.wav. Or even script this. Seem to remember doing this about ten years, yawn, ago ... (Could do some digging!) 2) TheSoX people were really nice. A "sox -force_channel_mask 4.0" could be requested though a request "sox -force_channel_mask abcd" that would allow any mask would be more 'democratic'.
