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?

If the motors are stalled, they will draw their stall current.
That said, there's pretty much no traction material available that won't slip drive wheels with 6 CIMS geared for 5 fps.
Drive trains are "traction limited" (wheels slip) for the most part. The amount of current drawn per motor while the wheels are slipping depends on your gear ratio. Going well above 40A per motor can trip the resetting breakers. Going well above 200A per system risks tripping your main breaker a bit too quickly.
