I'd been watching the steadily declining sales of Green Arrow/Black Canary, and reading something about Hawkman, along with the general discussion I've had with various folks at the store about how "resting" a character for a while can result in big sales (witness JMS's Thor, Kevin Smith's Green Arrow, etc.) and I came up with this:
Cancel the currently underperforming Brave and the Bold series, relaunch it as a new number one:
Brave and the Bold starring Green Arrow and Hawkman.
You could do the liberal/conservative road trip thing ala Green Arrow/Green Lantern with a character whose politics more easily fit into the conservative mold than Green Lantern, who always felt forced into the "establishment stiff" role in some way. You'd get two really popular characters who always seem to struggle on their own, but together, might be a pretty good pairing in terms of fanbase. Put 'em on a tour of the DC Universe, ala the Brubaker/Stewart Catwoman story. Have them re-join the Justice League when sales start fading to give it a boost. Bring in Black Canary, the Atom, Green Lantern and all their friends for one-off stories.
Ideal writer for this would be John Rogers, but he's busy with Leverage. Then there's Geoff Johns, but he's busy with writing everything else in the DC Universe. Definitely keep Winick and Willingham way the hell off of it, when they mix politics and the DCU you get the dull, plodding, borderline nonsensical "DC Decisions."
Anyway, just a thought. Not that I expect this to happen or anything, but just thought it would be kind of interesting.
