Could a County-class hull become an escort carrier?

Would a County-class cruiser hull make a good escort carrier?

It could probably produce a useful aviation ship, though escort carrier might not be the right classification.

A County-class hull could plausibly become a useful naval-aviation ship. The finished conversion might not properly count as an escort carrier because that label describes an operational type rather than merely a converted cruiser hull. Hull suitability determines whether the conversion can work. Intended employment determines what kind of carrier it becomes.
