This one is almost correct. Let's make a few changes:

ecasound \
     -a:1 -f:16,1,44100 -i file1.wav \
     -a:2 -f:16,1,44100 -erc:1,3 -eac:0,1 -i file2.wav \
     -a:3 -f:16,1,44100 -erc:1,2 -eac:0,2 -i file3.wav \
     -a:1,2,3 -f:16,3,44100 -o trio.wav

In other words when copying channels 2 and 3, we mute
the source channel (ch1 in both cases) after copying
the data.
