Charge current for a standby battery is low so charge circuit power dissipation shouldn't be much of a problem with this approach. In the rare occurrence where one might want to blast a charge into the standby battery, the isolation stuff could be shunted allowing full alternator juice access to the battery. Gezzzz we make things complicated!
