I'm pretty sure a couple guys have done it. The main problem is you can only use the alternator while engine braking since the engine must be spinning to spin the alternator. A good ecodriver minimizes brake use so much that this really doesn't allow for a ton of regen. Even if you did move the alternator to a driveshaft or something, the braking power it would provide is next to nothing.

In order to disable the alternator for any prolonged amount of time, you need a deep cycle battery. A starting battery will die very quickly when deeply cycled.
