Stug III G in Ardennes

Having almost zero knowledge about the Stug III, even when I always loved its look, I’m finally thinking on getting Takom StuG.III Ausf.G Early Production kit, #8004.
Is it possible to depict it as one during the Bttle of the Bulge?
Any good resources about units and cammo schemes?

As far as I can see, they G variant was produced between 1943 and 1945. The question is: how many early production vehicles would have been left at the end of 1944.
