I would go for it as I would go for Afterburn and other atmospheric reflections:
render a defuse pass for fire & smoke, and one for reflections with fume not visible to camera.
to get the alpha of the reflections, put a solid white color into the fume colors, and render them out.
now you'll have a fully white reflection, a color reflection, and a fume defuse pass.
