How about dusting off the G3 design in December 1936 and updating it? It seems a logical answer to the information about the new IOWA class starting. Begging the question...HMS Pinafore wrote:

With the USA building two 45,000 ton battleships within a year of the 1936 London Treaty being signed, the Royal navy is not going to take this lying down.
Unfortunately there is not much that can be done with the new King George V class battleships which have all just been started. The guns and machinery have already been ordered, so a complete re-design is totally out of the question.
However, it may still be possible to ‘tweak’ the existing design somewhat without having to delay construction of the vessels.
Your mission (should you choose to accept it) is to come up with a modified ‘KGV’ design that could be built within the same time constraints and without undue cost. The Royal Navy would still like to be able as many of the docks as the existing design can fit in for logistical purposes. It also wishes to retain a speed of at least 28 knots and a range of 14,000 miles at 10 knots.
Changes to armour and armament can be made, so long as they do not delay construction. There are now no limits on displacement - although the Royal Navy has a nominal maximum of 40,000 tons for docking purposes. Planned IOC (based on original historical estimates) are for King George V and Prince of Wales to enter service in 1941, and Duke of York, Anson and Howe in 1941.

Britain already has 13 dreadnoughts, all of which are armed with 15" main guns. USA and Japan are the only two nations which can seriously contest the RN battle line. 1937 Britain has plenty of time to contemplate battleship design.
Personally I think the RN should sink some money into ASW ships and aircraft at Malta to counter the relatively large (and growing) Italian submarine fleet. However Britain must eventually build at least two BB armed with 16" main guns to back up their diplomatic stance if they want to maintain their diplomatic reputation.
How would they differ from the NelRods and the original G3 design almost started?
Twin 4.5" turrets and solid sleeve triple 16" turrets seem likely. 30knots+ and 40,000t +treaty allowances for water/fuel.
Is a second aft turret possible/wise?
An extra 1500t roughly for the turret with mk2 16"/45 guns, although that doesn't include the extra 120-150 rounds/charges and storage. I'd imagine that more modern HMS Warspite refit style machinery would allow more space and weight for that.
http://www.navweaps.com/Weapons/WNBR_16-45_mk1.phpFurther work on this turret could benefit the Nelson and Rodney turrets too. I've underlined a major advantage of this existing turret design. A good start.
These triple mountings proved to be quite troublesome during their early careers due to their complex design. This complexity was partially due to the nature of mounting three independently sleeved guns, but it was also because of the British excessive use of interlocks in the ammunition loading and supply systems and by the use of a large number of swash-plate engines. There were nearly 50 mechanical interlocks associated with the loading of each gun. Although the anti-flash precautions were good in these mountings, the turrets still lacked flash shields between the guns. Magazines were located below the shell rooms, the first British ships in service to have this arrangement,
