Duster Rear Window Louvers

i am seriously liking that alot! how easy would it be to take the window out and trace it? i know its a mock up but, if you can make the slats evenly proportioned (pic) , i think you are really on to something here. in my opinion, the quarter and rear window louvers would look just plain awesome on a duster. if it was warmer out, i would be all over too!
