Still, that doesn't really explain much - some ancestor was a coppersmith maybe?

Is that an ad-hoc idea (nothing wrong about that) or did you find that somewhere? I'm asking because not only does Grünspan rather mean green patina than green splinter, but the name isn't common among German Jews, rather in Poland.
Actually, German "der Grünspan" means verdigris, the green colour layer copper is covered with through oxidization. It ha nothing to do with "der Span" (splinter), but is a corruption of "spanisch grün" (Latin "viride Hispanum").
Grünspan (or forms adapted to vernacular spelling of the countries where Families of that name lived in) is not a rare Ashkenazi surname). Herschel Feibel Grynszpan (with the Polish spelling of the surname), the young Jew who, disgusted by Nazi Germany's expulsion of his family to Poland (which would noty accept them so that they had to camp at the border), shot a German diplomat in Paris on November 7th, 1938. This gave the Nazis a welcome pretense for starting the long prapared November porgoms all over Germany.
Many Ashkenazi surnames are not from the time they were still living in the Rhineland (or, more likely from a linguistic viewpoint than the Loter theory, in the area around Regensburg), but from the late 18th century or the early 19th century, when Central European States such as Austria (in 1787), France (in 1808) or Prussia (in 1812) legislated that Jews had to take surnames in order to be registered "properly" like all citizens (for tax and military services etc.).
Not always were Jews allowed to choose their own surnames. Some legislatons (e.g. in France and Austria) expressly forbade that the surnames had any Jewish connotations (in the intention to make the Jews "true citizens" and equal to non-Jewish citizens). Often anti-semitic bureaucrats would take delight in pushing names with bad connotations in the vernacular on Jewish families. German Colour terms were easy and non-offensive choices for surnames, so Roth, Blau, Gruen, Schwarz, Weiss etc are frequent Jewish surnames. I assume Gruenspan was used as a variation on the ubiquitous Gruen.
