Sounds good to me. I'd just shut off the second battery during starting as 4 x 12gauge wires may be good enough for everything except starting currents.
Also, just in case you didn't know this, although you probably do, use the same amount of wires to the ground. (I knew a guy that would run thin wires to ground and negative and fat wires to possitive thinking that power only ran through the possitive wires.)
