Used nodes for all the bump based on Kitsu’s method of getting the normal channel of a procedural to work in the node editor. I think it turned out well. Though I wouldn’t mind a Pynode that randomizes the offset if you want more then one copy of the same texture or combine two procedurals and their normal before being plugged into a vector math node, but would like to make it look different even though you can sort of change it with the mapping and vector curve nodes.
