The fact that all those characters are analogs for older characters just underscores how completely unnecessary it would be to exhume them, whether or not your intention was to skullfuck the corpses and burn them, or merely skullfuck them. Do an Elseworlds series with the original Charlton characters or something. All the folks who gave a crap about the original Blue Beetle and Question have seen them morphed enough times that they won't care anymore.
Having said that, I laughed at all the Star Trek fans who wailed over the remake. To my mind, that took something deeply uncool and generally shit and turned it into something fun and exciting (albeit not something I'm particularly keen to see continued for the next 20 yrs...). If someone out there thinks they can take the Watchmen characters and settings, and do more interesting work than Moore and Gibbons, well, they're probably crazy enough to be worth giving a shot.
OTOH, if Dan DiDio outsources this to some hack like Judd Winick...I too shall take up the worship of a snake god and call venomy vengeance down upon him.
