Fast and good seakeeping on account of her length.  Can you not reproduce something reasonably close with 220m or less?

[Jefgte]

IMO, Too early for this kind of ship.

6x356-29kts-27000t...

Too much BP for armament / speed.

Wait 1918 to economise BP.

You could have the same ship for about 24.000t in 1918
----------------
1916 - 1BCx27000t
or 1918 - 1BCx24000t + 2DDs x1500t

Just my opinion...

;)

Repulse, but with smaller main guns, and more sensible secundaries.

[Guinness]

I personally am in the "no less than 8 main guns on capital ships" club, so I don't like the main armament. I think 8x12" would still be more than adequate for hunting older-fashioned ACs, and still be useful in a battle line engagement. The protection would be would still be useful against similarly armed opponents.

I actualy have somthing realy similar in a smaller lighter trim.

[Desertfox]

Too much armor and not enough guns. Can you stuff another triple turrent in exchange for a couple of inches or armor?

[Korpen]

Far, far too little back for the buck.
Considering that NS have no type 4 dry-docks or slips just the infrastructure upgrades to operate her would make her uneconomic...
As some people have pointed out, a 27 000 ton ship to carry just six 356/L40 guns is not cost-effective.
Also I think you are trying to mount far too many AA guns on her, you are basically adding 100-150 sailors on her without any real combat value, 4-6 75mm+ AA guns would be effective enough, and have the advantage of being able to use them against sea targets as well.
