A 1970s Renown as a carrier-group command ship

What would a 1970s Renown look like as a carrier-group leader?

It would carry a small gun battery, extensive air-defence missiles, close-in weapons, and a large helicopter deck with provision for Harriers.

A 1970s command ship based on Renown's hull would become a missile-heavy carrier escort rather than a preserved battlecruiser. The sketch retains perhaps a pair of 8-inch guns while adding Sea Dart, Sea Wolf, Phalanx, and possibly later Tomahawks. A large flight deck aft would support helicopters and allow Harriers to land and refuel. Propulsion would follow the carrier force, with nuclear power considered for a nuclear carrier group and conventional machinery for a conventional one.
