Put the following into your /etc/asound.conf or ~/.asoundrc:

pcm.multi {
        type plug
        slave.pcm {
                type multi
                slaves.a {
                        pcm "hw:0"
                        channels 2
                }
                slaves.b {
                        pcm "hw:1"
                        channels 2
                }
                slaves.c {
                        pcm "hw:2"
                        channels 2
                }
                bindings [
                        { slave a channel 0 }
                        { slave a channel 1 }
                        { slave b channel 0 }
                        { slave b channel 1 }
                        { slave c channel 0 }
                        { slave c channel 1 }
                ]
        }
}

and tell Jack to use device name "multi".
