At the moment it is pigment-function weathering, so if you can represent it as a
texture pattern it will work! You are limited only by patience and memory for
high-res meshes.

Vertical incisions could be done as a stretched pigment, and fractures as
crackle. I'll try it out tonight and see if it works. Preferential weathering
at corners and edges is of course more realistic, but I'm not sure how it could
be done. A translated turbulent wood could work on one edge, but not many...
hmm, I shall ponder.
