I think Rat's argument for why they should be the stars is a bit, well, stupid. It's like saying Chief Dan Matthews/Broderick Crawford should have been the star of Star Trek, as Roddenberry wrote scripts for Highway Patrol first. Appearing in an earlier work does not give one dibs on the leading role in all future works. They're lucky to even have had cameos.
Though I have to wonder, taking a look at the earliest EGS comics, just how bad was Dan's artwork way back in Junior High when those two were created?
