Hey cool stuff. I have a node pattern to show you that allows the selection of real noise from the built-in noise nodes, but making it keep a constant value within different regions. So, for example, you can have tiles where each tile produces a different but random color, but all the same color within that tile. Or brick. Or hexagon, or circle. Any region you can describe with math.

Basically you manipulate the offsets of any noisy node (FractalSum, fBm, etc.) so that the coordinate is a constant for whatever region you want. The resulting patterns are unpredictable in color but completely controlled in shape. You then use the controlled-random colors to feed as offsets into your color image map.

E.g. if you calculate such that the internal X value for your chosen noise node is Floor(U * 7.99999) you will get a "fixed" set of 8 different X values from 0 to 7 that feed into your noise node. If you do the same in the Y dimension, and hold Z constant, the node becomes a 2D rectangular noise generator.

Will demo when I have more time but you may be able to figure that out on your own.
