Time-base skew will be a problem.

The time base used for A/D's on two separate soundcards cannot
be expected to match.  Best is to use a soundcard that
records all four channels at once.  Won't the Hammerfall cards
( http://www.rme-audio.com/ ) do that for not too expensive
under ALSA?  Probably there are cheaper available nowadays.
