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.
