I don't think they were able to, since their aircraft never really touched down firmly enough to satisfy the weight-on-wheels interlock system. The aircraft won't allow the crew to reverse thrust until it settles into a "ground state" which we have today because some past guys managed to crash airplanes that way. Also, these guys commanded go-around power when they should have been hitting the brakes, so there's no way the flight systems were going to open the reverser.

Indeed, by the time the WOW settled into "ground", they had 2730 ft of runway left. :-/
