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

How much stuff do you need to run off of 12V? Surely somewhere there is a boost PSU to go from 6V to 14V. Just depends on the expected current draw.

I don't believe there is a way to get 12V while charging at 6V purely from batteries as I can't think of a way to do it without shorting the charging circuit. In your schematic the brown wires are shorting both the charging circuit and the batteries themselves.

However you could make such a setup work if you only charge one battery at a time, and use some type of crossover switch to change which battery is charging.
