You basically reinvented jackd with additional alsa_in and jack_capture or whatever recording tool (ardour?) a user intends to use. Just a quick walk-through: $ jackd -d alsa -d hw:0 --> fire up jackd on first card $ alsa_in -d hw:1 --> add second card $ alsa_in -d hw:2 --> add third card a.s.o. Then, use any jack capture client you want, including jackrec, jack_capture and ardour, just to name a few.
