Hypothetical situation time...

Lets assume somebody had an alternator disconnect that automatically connected and disconnected based on various parameters. Let's use the AutoSpeed BSFC graph as a reference.

So if somebody had 60% engine load and 2,000 RPM (green island) and they "turned on" the alternator which increased the load say to 90% load (but same RPM), then the BSFC would be in the red island.

Would the car get better gas mileage with the alternator on rather than off, since the BSFC is in a better range?
