You might need to think about this a bit more. Assuming you have a single phase motor, it will not reverse instantly. But if it is three phase , you just need the foot switch to swap two leads.

Right. But the motor still defaults to reverse rotation so all I would
need to do is step off of the switch, not toggle it.

But if you are using a single phase motor, it will not reverse until the centrifugal switch drops out.
Dan
Capacitor start single phase motors only need to slow to about 80%
full speed before they can be reversed. With the tap drag this happens
fast. I have done plenty of this on small single phase motor lathes.
