An Admiral-class hull was considered for strike-carrier conversion

Could an Admiral-class battlecruiser hull have been repurposed?

At least one hull may have been considered for conversion into a strike carrier, based on internal discussion surrounding the allocation of Ark Royal's construction work.

This conclusion is tentative because the evidence comes from how the hull appears in internal discussions rather than a complete surviving conversion design. Even so, those references suggest that carrier conversion was treated as a serious alternative use when shipyard work for Ark Royal was being considered.
