Was there a modified Dido-class replacement design?

There were several improved-Dido ideas, and a longer war would have created a need for one, but this exchange does not identify a single definitive design.

Several ideas existed for an improved Dido, although no settled replacement is named here. A continuing war would have created a need for such a follow-on cruiser. No dimensions, armament, or approved design history are supplied, so this is a general indication of further development rather than a specification.
