- - (Looks like the disconnect requires engine kill, but so be it)
Deep cycle battery
A/C recharge capability
- - (Configured for user convenience due to frequent use)
So far as I know, MetroMPG was the first to implement this on a petroleum powered vehicle. Of course every full EV has GPES but they are in their own league. "Alternator delete" already well enough known, but with a deep cycle battery pack and an efficient method of recharging it, you have a combination that can deliver a consistent mpg increase.

"GPES", I like it. It effectively makes a simple ICE into a crude and practical hybrid, you know? I hardly ever charge my charging system with anything other than the grid. The power I used for the 65 mile trip home yesterday came entirely from the solar panels my friend has on his house roof. Much greener than burning gasoline.
One optional addition to the "GPES" mod would be electrical load reductions (LED, HID, and such...). With load reductions I have driven my commuting distances in the cold dark without using the alternator at all. Your plans are even more promising for night driving because of the bigger deep cycle batteries you are considering.
