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.
i want to run basically a 12v accessory socket and a stereo. and you do point out a problem that i am mulling over now. the crossover wire that turns the set of batteries into a series set, shorts the charging circuit. and thats no good. so then yes i think your idea of using basically a 6v to 12v power supply to create a seperate 12v circuit is a better idea. that way i do not have to hook the batteries up in series. hell i dont even need 2 batteries just 1 big good 6 volter. on amazon they sell 6v to 12v DC to DC converters and they are 120. on ali express i see 500 and 700 watt units.
