Myoko Class Quad Turret Variant 2

This drawing was my first take on the quad turreted Myoko:

Because the Hiraga document hinted 12 barrels so either 4 triple or 3 quad turrets hence this 3 turreted version I show here.
I'm not sure it is possible to mount 12 barrels on 10.000tons but the usual splinter protection of the Japanese cruiser gun turrets and the shorter belt and deck armour compared to the 5 turreted original Myoko together with some other weight saving might be just enough to reach that goal.
Reduced ammo for standard loadout fewer torpedo tubes and DP-AA guns might be necessary as well.
