You could but you will be 2 short. 470=4 burners 6xx - 6 burners. Unless you have the 470 than you'd be up by 2. I think the IR rotisserie burner is the same size and BTU between them so the orifice there would work as would the side burner orifice. Then you need an LP regulator and hose, a few other little odd bits but it should be fine
