I played around a bit further with this "quasi K4" approach. And 
indeed, artificially changing the densities pulls the curves from one 
another and gives a smoother transition. But I think I like the first 
one better. Using the toner curve (i.s.o 4th K in the gray curve) 
allows for a much wider spread of selenium over the tonal range.

Another step in telling the wrench from the hammer ;-)
