A Shady Experiment in Blending

I've been watching various YouTube painters tinker with the forthcoming Citadel Contrast paints, and it's been Pete the Wargamer that I've paid particular attention to since his experiments with the Contrast paints are along the lines of what I'm interested in doing.  He mentions how he used the Contrast paints for a wet-blending method on a particularly nice example of a Nurgle-y vehicle.  It's because the Contrast paints take a good while to dry that this is possible.

Yesterday I'm sitting around trying to figure out how to get a whitish tabard to look nice and suddenly it hit me.  Shades and washes take forever to dry just like the Contrast paints, so what on earth is stopping me from doing a little blending while the shade/wash is drying?  I have to be honest; if I hadn't seen Pete the Wargamer do this with Contrast paints I would never have thought of doing this.  It seems to work pretty nicely as long as I haven't utterly slathered the shade over what I'm going to be blending onto.  I'll need to practice and tighten up the technique, but the 'prototype' results look decent.
