I would suggest that there are too many well defined stencils. You don't see the numbers on the fuselage ribs after the F models much, and in a late 1944 G-14 model you're going to see only the basics as they get painted and repainted so often.
Unless you have specific photographic evidence otherwise, I think all the red "press here" marks, the fuselage numbers, the red wing walk areas, and especially the "nur hier" markings would all be absent.
Many did not even have the "vorsicht beim cooler im haus" or whatever it says on the chin panel. By then the ground crews were quite well trained and they just did not need these, and never repainted them (or in some cases I'm quite sure they were never painted to begin with!).
P.S. Oboe, many places went "PC" a while back. You will see Japanese manufacturers obscure them like on the box art for the Hasegawa G-14 below the profile. I guess it depends on where the artist that created the profile lives.
