My recommendation to implement this is editing
/usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf and adding
a mapping "iec958-ac3-surround-51-weird" that is mostly a copy of
"iec958-ac3-surround-51" but changes the channel-map to the map you
want to use. Then you should simple be able to switch between the
normal and the weird AC3 profile.

(and don't forget to restart PA)
