Digital BW, The Print

I actually just tried what you're suggesting a few days ago. I loaded a
light black cart with yellow position ultratone ink and made a few test
prints. I could still see dots in the highlights, and I got some very
slight transition problems in the darker areas. The rest of the inks
were regular MIS Ultratones. I didn't bother to do extensive testing on
this, but I still have the cart here so if there's anything specific
you'd like me to try I could make some more tests and post scans of the
prints.
