The problem with that is your running only off battery which with a load will be around 12v, maybe less depending on load . The alternator only puts out amperage according to load so the regulator adjusts this, it does though maintain higher voltage value of around 14v or so. This does make alternator put out some but at same time any load , the amperage will be more with lower voltage .
You could implement what Honda/Acura does by using a dual output alternator were it output is reduced on low loads and only goes into high mode with decent load on , like AC, headlights etc .
