You might be able to do it with linear motors. The problem there would be the reliance on the safety brakes in the event of power outages (not really a problem

  Mount what amounts to an elevator system on the linear motor, but it never goes up and down. So you suspend a standard otis elevator from the linear motor. Power fails, linear starts to fall, lands on top of the traditional otis with its emergency brakes holding the whole works up. There's no reason the cable between the otis and the linear has to be 200 feet for the linear to build up speed... make it, perhaps, 3 inches and a nice spring arrangement. I bet it would still be pretty scary to be in one of those during a power failure. So put hybrid batteries on the linear motor so it can just keep on running during a power fail, perhaps programmed to do nothing but a normal controlled descent to the bottom doors. if ($powerfail == 'Y') { ignore_all_floor_selection_buttons_higher_than_this_floor; }
