Basically, the CIMs draw the same amount of current at stall regardless of the gearing so any stalling of a 6 CIM drive is just as dangerous.

Am I right in that assessment?

Yes, stall current is stall current. Ideally your low speed gear ratio in your 2 speed drivetrain should be as fast as possible while still being traction limited. That gives you a higher speed in low gear without sacrificing any pushing power.
