Could a navalized Tornado have replaced Phantom and Buccaneer aboard CVA-01?
Short answerOnly through such an extensive redesign that it would effectively become a new carrier aircraft called Tornado.
NotesCarrier landing is a controlled crash that imposes loads a land-based airframe is not built to absorb. A naval Tornado would need a redesigned structure, strengthened landing gear, arresting equipment, and provisions for catapult launch. Those changes propagate through the airframe rather than forming a small bolt-on package. The answer therefore distinguishes a genuinely naval aircraft program from a superficial conversion of an existing type.
