I don't have a variable tone inkset set up now.  So I can't test this.    I'm wondering if applying 2 curves, one each to 2 test strips, and then putting one of the test strips as a layer at 50% on the other might work better.  At any rate, you probably see what I'm trying to do -- get a blending of the curves.

Tone is one issue, but the other that I had in mind was to be sure the 21-steps were still separated -- no totally flat spots or posterization.

The ICCs I made were made with QTR's Create ICC-RGB.  See

You basically drag both the linearization data and the curve into the Create ICC-RGB icon on the desktop.  The curves are entered via a little image file: rgb-raw-16.psd.  You should be able to combine the curves on this file just like you'll try to do on the 21-step test file, a print of which is where you get the linearization data.
