A random thought, not having followed closely enough to know if it has been suggested, but what about treating crew similar to the weapon factor using two lines, the weapon factor and batteries/bearing being translated to crew factor and sections/frozen watch.
So the crew factor can actually be used to measure something, like combat effectiveness, while damage reduces sections (batteries) before impacting factor and frozen watches are subtracted first (like non-bearing batteries). A ship could be allowed something like an action (battery attack, specific defense, maneuver, etc.) or damage control action per crew section. Crippled (reduced sections) ships would be restricted in total actions, and when reduced to a single section as the factor is further reduced the remaining action suffers further from less effectiveness.
...or is that less errata/minor addition and more in the realm of (perhaps needed) a larger rules rewrite
