Main breaker tripping, dead CIM

Not with the breaker tripping. You'll lose less voltage, but 120 amps is 120 amps.

Say running 10 gauge from the PD board to the motor controllers, and keeping the 12 gauge lines coming out of the CIMs as short as possible?

Your battery will drain less quickly, but as I said 120 amps is 120 amps.

Is there a software solution that might also help, say by turning off a CIM or reducing power when a stall condition is detected?

That's an idea, but it would be hard to implement without impacting performance.

Do any of the motor controllers have a way of reporting current draw or load back to the main system?

Jaguars with CAN do, and you can add external current monitors to any motor controller.
