For example, even a relatively small asteroid impact (~10 m radius) would imbalance the spin gravity system by subtracting mass from somewhere, which would result in the entire system decaying within a few days without load shifting (0.2 rotations per minute is still a rotational velocity of more than 20 km/s).

The effective gravity was given as 0.2g, and the diameter 650km, so the rotational period is about 2530 seconds, or ~0.024 rpm. The rotational velocity of the rim would be about 800 m/s.
