InkThrift CL Black for Piezography K7?

I’m diving into un-replied posts that were buried by our old forum software back in the day.

I actually used to use the Matte Black InkthriftPro ink before I worked here. It got to a dMax of 1.8+. After coming here in 2016, we released our Ultra-HD-MK carbon ink and this gets to 1.86 on some matte papers. It’s by far the blackest inkjet ink in the local solar system.

What’s the feasibility of substituting the InkThrift CL Black for the #1 black in Piezography K7 in order to get a higher Dmax on matte paper? This would be for prints intended for portfolio use only, not for prints put on display.
