You've mentioned the metamerism problem several times.  
But metamerism is a physical property of the ink.  When any two inks 
have a different shape to their spectral response curves you have the 
risk of a metamerism.   Pigmented inks tend to have "peakier" 
response curves so they have more risk of metamerism than dye-based 
inks.  Are you saying the dark cyan and dark magenta inks have a 
response curve with a different shape than their light cousins, so 
that eliminating them fixes the problem?

Thanks for all the other info!
