Overweight penalty is only a huge deal in Surface BB combined fleet (team1 ) and carrier escort combined fleet (team 2)

Generally speaking in normal operation 6 ships. High level Kongou class can even use 46cm, if you dont feel that safe, 41 is fine.

Coming back to the point above, Surface BB fleet should not be using Kongou class anyway. If you do have to (no yamato class) Krishima is usually go to choice. She has good FP, so 35.6 cm is fine.

That is why it iis only recommended to upgrade 2 35.6 cm (for Krishima).

Even in combined fleet, it is better giving other Kongou class modfied 41cm. The increse in FP is worth it for a few % of less accruacy. (Emphize modified 41cm and 91 ap shell and high level ship)
