Did Germany need fleet carriers in the Second World War?

Given Germany's geography and enemies, did a fleet-carrier force make strategic sense?

Not as a centerpiece; Germany was better served by long-range surface raiders, perhaps with limited carrier support to reach the open ocean.

The proposed force structure starts with Germany's geography and need to reach the Atlantic rather than copying another navy's fleet. It centers on 15,000-to-20,000-ton long-range cruisers or raiders instead of battleships and a conventional carrier force. A carrier could provide air cover while those ships passed through constrained approaches and then help them break into open water. It would support commerce warfare instead of serving as the centerpiece of a battle fleet Germany could not employ safely.
