Is NIGHTWING In Steven McQueen's Future After All?

Steven R. McQueen, a regular on The CW's The Vampire Diaries is leaving the show later this season.  Showrunners for the vampire drama gave indication today at the Winter TCA's that The Vampire Diaries is in it's third and final act of storytelling, despite the show being renewed by The CW for one more season.  With the show continuing and McQueen's early and unexpected departure, fans are already speculating that McQueen is gearing up to go after (or has already landed) the Nightwing role on TNT's Titans.  As covered in the recent Supergirl news, TNT is a subsidiary of Time Warner, make it possible (on paper at least) for Titans to have a connection with Arrow, Flash and CBS' Supergirl (perhaps even the newly announced VIXEN animated series).

Fans will recall that McQueen heavily campaigned for the role of Dick Grayson and had many convinced that Nightwing would turn up on Arrow.  That didn't come to pass but perhaps the TNT Teen Titans drama gives McQueen's Nightwing aspirations new life? 

The Vampire Diaries showrunner Julie Plec says the door will be open for McQueen to return for the show's final episode or some other significant barring McQueen's busy fighting crime.  "[McQueen] will  always be welcome to join [The Vampire Diaries] for important events — unless [McQueen] finally gets his wish to play a superhero and he’s unavailable."

I would personally be more skeptical of this but Plec's offhand reference of McQueen's desire to play Nightwing could very well mean that McQueen is in the running.  Is Plec implying that McQueen is leaving The Vampire Diaries to pursue Nightwing and if he doesn't secure the role then he's free to return?
