Re: 6v positive ground with 12v output! Best of both worlds

I don't know if they are still made but there used to be aftermarket solenoid add ons available for this very purpose.
If no luck finding one maybe you could reference their wiring diagram for your implementation. Instead of just limiting the 12v to the starting circuit as they do, make provisions for the extra needed to power other items you wish to include.
One thing you do need to watch out for when charging batteries in parallel is they need to be somewhat close in spec and condition. If one has a significantly higher internal resistance than the other, the charging current will not be split very evenly. In that situation one could be overcharged while the other is always low.
