Not really. Watchamn may have used the Charlton heroes as templates, but it was really a study in super-heroes neurosis. Most characters had very little to do with the actual Charlton heroes. Rorschach was a psycopath, Nite-Owl a well of insecurities, the Comedian a sociopath, and so on... Captain Atom was a super-powered military man action hero, not the juiced up isolated from humanity god Dr. Manhattan was (IMHO, a one trick poney, that wouldn't work on an ongoing series,as the Nu52 Captain Atom seemes to have proven). Unlike Nightshade, Silk Spectre didn't have any powers and was basically eye-candy, , and there were no super-villains for them to fight, after all, it was supposed to be super-heroes in the "real world" (as pretty much everyone, I love Watchman, but the concept in itself is pretty dumb, and Moore's idea of what the real world and real people are like is downright sad).
Honestly, I think a US govenment funded and controled super-hero strike unit using the Charlton heroes could be great. Forget Watchman already, and give us great super-heroes in a super-hero world.
