could superimposed/Superposed Turrets (stacked) ever be a good idea

As you can see there are two types of turrets, mixed and same caliber turrets.  That is a turret with two turrets of the same gun size.  The other is mixed turrets with a different caliber in each turret.  You also have turrets that are fused into a single unit and turrets that can move independently of each other.  I am aware of the Smolensk which in game has a similar idea, but most ships leave all guns in anything larger the 40-50MM on the same level.  Only small size AA guns seem to show a straight over under or even over under off set pattern.  Above are two real life mixed stacked turrets by the us navy that show that in case of mixed size guns its a bad idea.  After that two designs with three and five gun stacked turrets could this have worked or failed as the above designs did.

I dont think that was ever duable with the BB caliber guns, stuff like Smolensk prob could have been done but not much bigger then that

I suspect, in order to make it theoretically feasible, the resulting construction would be make the ship so top heavy that it would become unstable.

That and the taller turret with bigger front "holes" makes for a much better target for the enemy guns...

Depends on the leeway in the design, but something built to treaty limits would almost certainly not be able to accommodate guns high up in the ship.  

I'm trying to think of the ships in WoWs and what the largest weapon is on top of a turret. We have Hood's UP launchers, lots of 20 and 40mm Bofors, perhaps a 76mm gun or two, but nothing bigger. Perhaps sensibly. Who would want to be trying to lift 4 inch shells up the side of a turret, under fire?

It is not only a question of size , gun interference, redundancy, complexity, fire control, large opening in hull gives problems structurally, TDS will be narrow if you have 5 barrels.

That moment ^^^^ was when the "American Standard" style battleships said, "Hold my beer!" and grew some amazingly "plus-sized" curves.  🙂 

More seriously, though, there are legitimate seaworthiness considerations when contemplating designs with turrets that are placed too high upon in the hull.
As others have mentioned in earlier posts within this topic.

It's been tried in real life...

https://en.m.wikipedia.org/wiki/Kearsarge-class_battleship

https://en.m.wikipedia.org/wiki/Virginia-class_battleship

In both cases, it was found that the use of one set of guns disrupted the other...and that it was practically impossible to target separate targets with the superimposed turrets.

In practice, the guns just all fired at the same target. Additionally, the perceived advantage of faster rate of fire of the smaller gun set disappeared by the time the ships entered service.

And, bonus, British gun turret patent (need a 20-inch guns 😞

Perhaps in real life but in game a stacked or fused turret with the same size guns could have advantages or maybe not still just about every possible gun placement has been explored.
