Graf Zeppelin could keep British carrier construction moving

Would a German carrier accelerate British carrier construction and change the classes ordered?

Probably: carrier construction likely continues, Implacable may expand, and a later design could combine Audacious- and Malta-like features.

Churchill could still press for a capital-ship construction pause, but the Royal Navy had already separated carriers from capital ships in those arguments. A credible Graf Zeppelin threat would strengthen the case for continuing the Illustrious class and perhaps expanding the Implacable class. The next British design might combine features later associated with Audacious and Malta. This would change the wartime construction tempo and the path of British carrier design.
