Isn't it possible to do this with the auction house only?
a) 3 x Spirit of Harmony --> Restored Artifact --> Crate of Tol'Vir Archaeology Fragments
b) Tol'Vir Hieroglyphic
Spirit of Harmony is 45g and Tol'Vir Hieroglyphic is 220g. I'm only 585 in Archaeology now, so I don't know how much Fragments I get from a restored artifact, but this path looks stupidly expensive, if my assumption is right. I can probably throw a spectral tiger at it.
I guess I need to try it once first, as I probably got a few things wrong here...
