as there is no ready operator (or a LADSPA plugin) for doing this,
I'm afraid this will get somewhat tricky:

ecasound -z:mixmode,sum -f:24,2,44100 -a:l,r -i foo.wav \
          -a:l -erc:1,2 -eac:0,1 -a:r -erc:2,1 -eac:0,2 \
          -a:l,r -o bar.wav

So on chain 'l' we copy ch1->ch2, mute ch1; and on chain 'r' we
copy ch2->ch1 and mute ch2, then mix 'l+r' back together.
