Are there any longer rails that will fit on the S-System ... Either fitting along the whole side of the RIS or filling in the rest of the empty space left by the rails that come with it?

Check out WGC's online shop from Hong Kong. First Factory makes parts specific for the Marui M4S. They make longer side rails and bottom rails. ..
