I think it should look like what YOU want it to look like. Having said that, have you considered the "other" type of sidepipes? I mean the ones that had the four header pipes coming out under the front end (some were real, some were fake header pipes). Your picture shows a "gap" at the front, under your door. Perhaps this would bridge the gap. and fill the entire rocker panel.
Either way, I like the idea. Post some pics when you get'r done.
