Bleeding Cool reports that the publisher is reviving the project and compiling a shortlist of potential creators to helm it.
Darwyn Cooke is allegedly being considered as artist for two Watchmen miniseries - set before the events of Dave Gibbons and Alan Moore's epic graphic novel - and as writer on a third.
J Michael Straczynski, JG Jones, Andy Kubert and Brian Azzarello are among the other names on the list. It is unknown whether any of the creators have been approached by DC.
Gibbons and colourist John Higgins are expected to be involved in some capacity should the project go ahead. However, Gibbons told Digital Spy in 2009 that he previously turned down the opportunity to work on Watchmen spinoffs.
"DC did once float the idea of doing some spinoffs from Watchmen, but once Alan and I expressed our disapproval I think they realised it should be left alone. I think if you do anything else to Watchmen, you're going to risk diluting it rather than enriching it."
DC is yet to officially confirm any plans for Watchmen prequels.
