You might run afoul of one instance of Direwolf opening the ALSA device
for the sound card and locking out the second instance unless you do
some trickery in the ALSA configuration files to present the UDRC/DRAWS
as two separate audio interfaces.

This is doable of course, just may require a bit of research.
