Could old Town-class cruisers become enlarged destroyers?

What might Admiral Henderson do with four pristine old Town-class cruisers found in 1938?

One suggestion is to convert them into large destroyers, perhaps with 4.7-inch dual-purpose guns, resembling enlarged Tribals.

A hypothetical discovery of four pristine old Town-class cruisers in 1938 prompts a proposal to convert them into large destroyers. Their operating characteristics are the reason offered for choosing that role. A possible armament is 4.7-inch dual-purpose guns, producing something like an enlarged Tribal-class destroyer. The ships' pristine condition is part of the scenario.
