Directing no, except for his framing skill (Kershner himself prised him for this, and he’s definitely better than “J.J. Closer-to-the-camera Abrams” in this regard), I’d like him to contribute to the plot, one way or another (unless he wants to turn Star Wars into a “soap opera”). I remember that in a very early interview he said he wanted each Star Wars’ episode to be directed by other directors, except for the first and last movie which he wanted to personally direct, but I doubt he’ll ever be back now.
