I haven't tried doing what you are trying to do, but I don't think it would be feasible for a few reasons. 

First, the amount of solvent (whether water or flushing solution or something else) required would probably be far more than a printhead would be able to provide. The paper would absorb a fair amount (all of it?) before you would see any runoff from saturation. This is especially an issue as the droplets aren't all laid right on top of each other, but with space in between. 

Second, the paper path is flat. This means you'd need even more fluid & it wouldn't run, just spread out the ink. Given what I said first, that would be a lot of picoliters! 

Third, if you could lay down lots of solvent, a printer with dye based inks might show some running/oozing of the colors. Pigment based inks would require even more fluid as you'd need to float the particles to get any watercolor type FX.

I do a little painting & think that you might be better off trying applying water (or whatever solvent you might choose) with a brush. You'll have control over the volume applied & can vary the tilt of the surface to control any running/oozing of the colors. 

Hope this helps even tho it isn't exactly what you asked for.
