[Korpen]

If transporting troops to shore she is far too large. If not she do not need the landingcrafts.

[P3D]

Agreed. This is a liner/troop transport not an assault vessel.

Don't use bulges, it won't save you any displacement, and  you need all the hull volume you can get for the troops.

Did just see the bulges!  :o
Far, far too much, you are transporting soldiers, and that is volume rather then weight critical cargo. So you will want as much superstructure as possible. You can make her much narrower, and if you change the trim you could improve the stability as well.
However if the ship is intended for strategic transports I would increase the speed, and the cruising speed. With 1916 engines a range of about 6-7000nm at 23-24 kts should be possible with that payload.

EDIT: post applies to the large version.

Ain't it funny, Nverse has faster troop transports than 1940-1950 IRL.

Not really surprising, as far fewer Nverse powers have the ability to provide the kind of total sea control the allies could in and after ww2. If one cannot be sure to guard the transports, making them faster so there is less time for a threat to catch them on the open sea makes allot of sense.
