You could use a pattern or image_map to sample from and modify your paint layer
according to that - have a function modulate the color or the difference of the
paint layer.
Apply filter or transparency to the top layer according to the intensity of the
knot - maybe with a pattern mask or proximity pattern of some sort to keep the
real-look.
Use an average {} pigment pattern to work it in, along with the normal.

That's all I've got so far before morning coffee   ;)
