Many people that commented on that thread were being negative towards it, but I personally think that it would be great. Imagine getting 25+ MPG in the city on a 426 horsepower beast without loosing any performance whatsoever (minus the added on weight of course).
Aftermarket hybrid engine that plugs into any car? I think you'd have more luck with gasoline pills...at least those are cheaper.
