I'd think the new SS file is fine and pay the extra tonnage as you say. Might make for a good IC story.

In my opinion...these have been at sea 2 years, they are not building on the ways, not something 'in development'.

Story is they are a pushed design, the French were trying to squeeze maximum out of the hull, decided to forgo superfiring. BC is dinky, short belt, speed is high, desired good seakeeping, so they cut out barbette armor and enhanced stability. There have been odder decisions made in naval design.


Not wedded to it, but thats my 2 cents.

My general preference would be to deal with the fixes in a rebuild, but this particular error can't really be handled effectively in that way.
