I've used a circuit like you describe in the past and if I recall, the designer had specified a mercury-wetted contactor whose drop out time dictated the reverse time.
The fact that he used a mercury contact tells me there's some big-time arcing happening here and a mechanical one won't hold up.
Incidently, when implemented with the proper components, this is a cheap-and-dirty way to stop small motors quickly. However, with today's gadgets, there's certainly better ways to do it.
