Not as good FE-wise, but much more practical, is an alternator kill switch. You disable and enable the alt's field wire at will, for example the last few kilometers before home (where you can top off the battery), or turn it off when idling and on when engine braking, getting a charge for free.

You still have some losses, since the alternator and its belt add a small load to the engine, but you reduce the electrical load to zero whenever you want. And since your car doesn't have any electronics, then the constant switching between 12V and 14.5V shouldn't be a problem.
