The only way this could work and not completely suck if it's a ploy by Imperials/Sith remnants to try and restore the Empire to former glory by using an imposter/cloned Vader (ie: Thrawn does this, same thing with Palpatine too I think in Dark Empire).
But he couldn't be a central character he'd have to be a decoy. And of course Luke would be prompted to get to the bottom of it, and perhaps he's kept Anakin's identity secret for so many years that the truth coming out could shake his standing in the New Republic/Jedi Order.
That actually might be kinda interesting.
