a while back I read about a product that replaced the alternator and would kick in when the engine was under higher loads, I'm pretty sure that system just ran off the normal battery, bumping up the voltage and adding a dc/dc converter would be reasonably easy, other then you would still need a normal battery for starting as the dc/dc converters get pricey if they can handle that many amps.
