Implacable could take an angled deck at prohibitive cost

Would an Implacable-class carrier be suitable for an angled-deck conversion?

It was large enough, but the age and cost of rebuilding the hull would make new construction the better investment.

The Implacable-class hull was large enough to receive an angled flight deck in physical terms. By the time the conversion became relevant, however, the hull would already be old and would need extensive work around the flight deck, lifts, machinery, and aviation systems. The cost would buy only a limited remaining service life. A new carrier would offer a cleaner arrangement and better long-term value.
