Could Admiral-class hulls have become aircraft carriers?

If the G3s had gone ahead, might the unfinished Admiral-class ships have been converted to carriers?

He considers the conversion plausible and suggests the Admiral-class hulls could have replaced the smaller interwar conversion carriers.

The unfinished Admiral-class hulls are presented as plausible candidates for large carrier conversion. That possibility rests partly on Cammell Laird being described as a large-carrier specialist before completing Ark Royal, which suggests that serious conversion study may have preceded the treaty settlement. The claim remains a hypothesis rather than evidence that a conversion was ordered or begun. If completed as carriers, the Admirals could replace Courageous, Glorious, and Furious and leave Hood as one surviving member of a class still represented in wartime service. The industrial clue supports a plausible alternative carrier force while leaving the absence of an order or conversion work clear.
