If reverse has been selected you stay on the runway and stop. If the obstacle is so close that you can’t stop in time with maximum braking then you most certainly can’t miss it by trying to get airborne again.
Cranbrook took off in time to miss the snow plow - had the reverser stayed stowed (which, as I noted earlier, has been corrected on Boeing aircraft), it would have been a non-event. If you're going well north of 100knots, it takes a long time to stop vs. taking off again.
Granted, not something that any sane person would plan, but with faced with a certain collision at speed, or getting airborne again, you need to make a rapid decision and then just pray it's the right one. The aircraft design shouldn't be the limiting factor.
