The Myriad of British Battlecruiser Designs

Hello, I am wanting to look at WoWs again and remove their creative liberties once more by asking about the British Battlecruiser designs they have and the designs are based on what their real specs were and if they still hold true to what they are in any extent at all:
- Rooke from what WoWs says is based on the J3 Design
- Hawke seems to be based on the K2 and K3 Designs
- Duncan is based on a G3 Design
- St. Vincent is based on the I3 Design
Does anyone have what these designs looked like and what there historical armaments are?

There's available information about all of them either from internet and books:

I 3 looked something like this:

Long story short, St. Vincent is pretty close to its historical representation, apart from "hypothetical modernisation". As is Duncan, although she's based on the early version of Design G3 rather than the final one (the final version had 406mm guns and was slightly smaller).
Rooke has different main guns in game — WG gave her 15-inch 45-caliber Mark VII guns designed for the future King George V-class in 1930s. Historical Design G3 had 15-inch 50-caliber guns which didn't have any official designation (and were probably notional only). Otherwise, she's good.
As for  Hawke — she's a hypothetical shrunken version of Design K3 which never existed in real life. Historical K3 had 3×3 457mm guns, and I found no mentions of a change to 406mm guns being considered for it.

Also, those ships' "hypothetical modernisations" are somewhat dubious: the combination of installing 114mm DP turrets and retaining the 152mm single-purpose turrets doesn't quite make sense, as is keeping the submerged torpedo tubes.

And as it was pointed out above, the information on the historical designs can be found pretty easily.

The best image of G 3 is in Norman Friedman "The British Battleship 1906-1946" pg 211 . IIRC, it is an image of the original plan.
