nope. the hammerfall is configured to receive S/PDIF from one of 3
possible sources: the coaxial connector, ADAT1 or the internal pins
(for digital cd output). it cannot receive S/PDIF from two sources at
once.

if you want to do this, i think you will need a format converter to
convert s/pdif to adat, and then use any card that handles at least
one adat connector (8 channels).
