Yeah the GL thing would be almost worst case scenario, particularly in how Hal is now regarded. Other than his die-hard fans, he's pretty much passe as far as the mainstream is concerned, an outdated boring character from another era (although full disclosure, I personally still like Hal, and the current Morrison run is nothing short of awesome). Point being, it would be downright awful if they just started creating a ton of Supermen thereby turning the original in to a relic.
