Topic: combining Digi9652 and a HDSP9652

I have already a HDSP9652 card and would like to expand my channels from 24i/o to 48i/o
I can get for cheap a Digi9652 card, so question is:
can I run these two together and expand my channels to 48i/o on one application?
if this is possible, how to do this?
installing and running sync.
