somehow, it sounds feasable, but this is certainly one of those ideas 
which prove themselves more difficult in implementing them as one thinks 
at the beginning. You probably won't get away without some manual 
interaction, e.g. deciding which color-ranges to convert.

BTW, if it is not so important to use exactly that picture, but just to 
have a marble stone pattern, you might try out the procedural stone 
color patterns I've provided in my 2002 workshop contribution (available 
on the radiance-online site). Here you can set the rgb values of the 
color-map explicitely to the ones you need.
