Why unrestricted British carriers might resemble Implacable

Without treaty limits, would Britain build something like an armoured Ark Royal instead of Illustrious?

The expected design is closer to Implacable: an armoured carrier with two hangars, potentially given more height when treaty displacement no longer constrains it.

An unrestricted British carrier design is expected to combine an armoured hangar structure with two hangars, resembling Implacable. Removing the treaty displacement limit could also allow the full hangar height associated with Ark Royal. Supporting the armour would still shape the hull and internal arrangement. Unicorn-type ships could retain useful roles in trade protection, service with Dominion navies and duties that did not require a large fleet carrier. A larger new carrier force would also let older ships such as Courageous and Glorious take secondary tasks. Those possible roles depend on the hypothetical building programme.
