Just to do double refraction wouldn't require much effort at all. (the 
dispersion feature already does a kind of multiple refraction, for 
example)
Making it direction dependant would be harder, but not too bad. 
Simulating the other polarization effects would be quite difficult. The 
thing is, it is just very special-case...you aren't going to find many 
people interested in it.
