Irregardless of legality, it would be a bad idea to totally depend on a regen braking system as you've described without having the hydraulics there in case something goes wrong.

As mentioned above, you can set it up by making it kick in when the brake lights go on very easily, and I'd think it possible with the right gearing to make a good strong traction braking system to charge an onboard battery and reduce your dependance on the friction brakes. I've thought about doing something like this on my minvan (lots of space underneath and a dead axle anyway) but I would consider losing my brakes a bad idea.

FWIW locomotives have used this system for years for going down long gradients, but they don't use it as the sole means of stopping.
