In search of better Cherry tree's 'or' what the Navies of the world could have built Post WNT

Charles Evans Hughes and Arthur James Balfour and others are sitting in a room in Washington feeling happy they have nearly completed negotiating the treaty that will save the world from a potential arms race.
But Balfour has in part of his mind the fact that he is about to sign up to a treaty that will mean GB will have to build 2 more expensive battleships for the RN.
Somebody has a sneaky idea and passes it to him quietly, why not ask if we to can save a bit of money, after all that's the idea of the treaty isn't it?

What about if we restart the revised admirals? Using the scrap 15inch guns we have already paid for even if that means that we might have to go slightly over 35,000t would that not be reasonable after all look at Hood herself she is huge but you all realise that she isn't really much stronger for that. (and USN/IJN already has the plans for her)

So agree to 8x15" and an exemption to the 35,000t limit to let the "Hood semi-sisters" be completed.......

Then build this,

How revised are we talking regarding the Admirals? Just the otl improvements they had planned or some more stuff? You redesign the Admirals enough with the same rough specs (8 15" guns, 30 knot speed) we'll probably end up with a Vanguard with some armour shaved off.
And I understand why B turret on the G4 isn't superfiring but good god I can't stand them giving me vibes of those godawful U's :p
