You could do it the ******* way. Find some used plywood, cut to shape (doesn't need to be exact), and, actually nail/screw it onto your Patriot.
I may be wrong but I think I may have seen some "woody" kits at one time but I can't say if it was for the Patriot or not. Maybe SuzQ (or any other brave soul) could do some Photoshop rendering to see how the Patriot would look.
Here's the kit for the Commander. Doesn't look bad in my opinion. Just too expensive though.
