Yes there would be. HUD merely enables the pilot to fly head-up and see instrument information while looking through the window at the same time. It doesn't solve the problem, of actually seeing what is in front of you. There is a formalised requirement that the minimium visibility for pilot to obtain sufficient visual reference of outside world so that s/he can correctly judge the aircraft position, velocity and trajecotry in order to land safely is 300 m. With a HUD and 200 m RVR, there still woul be no benefit. Autoland can solve this. Actually, have solved this 40 years ago.
