A suitable 1941-style British light cruiser

I would say that a suitable British light cruiser, to be built as part of a program that included my battleship, battlecruiser, and heavy cruiser designs, would be about 12,000 tons and have 12-6in QF and 12-4in AA guns, with a suitable light AA armament, as well. We could probably live with a 2in deck and 4in side armour. I would want to see a 34 knot speed and a range of at least 8500nm.
