When you make gradual steps between two ink mixes like it is
already done with the slider of QTR there isn't much needed. A
third one added will increase the complexity as it is no
longer a one dimensional path and I expect that you can't
control that without a kind of color engine. In that case it
might be easier to go for something like LittleCMS as it also
could cooperate better with the (semi) ICC profile creation
of QTR. This would allow interaction between sliders and a
preview window too. Of course this comes close to the Advanced 
B&W menus of the latest inkjet printers. The last lack the 
transparent calibration of QTR though.
