well...
I think your biggest problem would be paint application. I sure somebody has done this well, but I don't remember ever seeing it :

Color choice would be the simple part - any contrasting dark and light wood color should do the trick.
Have you considered carving the prop?
I've done it a couple of times and it's not as hard as it looks.
I laminated 5-6 pieces of 1/64 in plywood to build the stock using CA. I then glued a scaled front view of the prop to the front and carved the outline.
then just start whittling/ sanding.
Makes a VERY nice addition to a model
I'm still wondering how to pull this off with a "virtual" model.
