Shoot the girl with a nice strong backlight so she clearly has a light source behind her, reflecting in hair etc. Don't attempt to capture light beams or atmosphere in the green screen footage.
Generate the light beams and atmospherics in AE. Beams can be created with CC Light Burst or Trapcode Shine. Fractal noise can be used to generate smoke or mist.
