An Idea Concerning Rek' Sai's Ult (or Bowling Ball Rek'sai)

Do you all think it would be a good idea if enemies in the path of Rek'Sai's ult get pushed back (in the direction she is travelling) and stunned for a small period of time? Using a well placed tunnel, she could ult down a lane before a teamfight and bowl over the opposing team.
