get the DHSN pair and try your luck. Worse case is that you don't get the snow, but the positive is everything else is a morph... Axanthic, Albinos, DHSN, etc....
Actually, breeding a DH for snow pair together will still yield normals in the clutch as well. And POSS DH's.. But yes, you could wind up with albinos, axanthics, albinos het for axanthic, axanthic het for albino, double hets, and normals.
