Agreed the up gunned County looks very nice.
Been thinking what may look ok and be a bit of a play on actual events, would be a British cruiser front with a pair of Mk26 6", Tiger superstructure, topped off by a Type 984 radar and a Long Beach aft and mid section, including Talos, the nuclear propulsion system and provision for Polaris. Same concept that saw Dreadnought being built with basically a Skipjack rear and the R class with their US missile sections.
These ships could have started out planned as the UKs nuclear deterrent instead of the Polaris submarines and evolved into flag and fleet air defence ships with the Polaris spaces used for Tartar. thinking of doing something along this line with a Revell Tiger, Shapeways backdate conversion and a Dragon Long Beach
