Well, maybe...  Some emulsions might do better under certain 
illuminating colors.

AND.. One might find that running noise reduction software on each 
channel independently COULD result in a cleaner final image than  
running it on the merged greyscale.  In fact, one might create profiles 
for each channel in Neat Image or Noise Ninja..

Of course, that could also be a MAJOR workflow pain in the butt..
