It's always worth a try. A lot of fish don't hold their color after a few ours of being dead, and the colors don't come through on a backing. I tried with brook trout, it went from a colorful skin of black with dots of blue, red and yellow, to a grey color by the time I got it home with a hardly any coloring remaining. The muskee may be different, either way it would still work, just may not be the same as it was on the fish. I say try it and find out.
