Ok, I just thought about 1945 remodel version of Nagato.

It will be pretty same ship but will have 2 extra T slots (as Nagato had 12 127 mm
guns in 1945). Anyway R slots in remodel should accommodate Type 90 16.1" guns. 3
binds + L 16.1" turret. 327 + 3*8.1 - > 352 R. Perhaps also ability to put bigger
engine should be considered.

Type 90 have a bit less range but more dmg. Either way Nagato will still have
advantage over all except KM triple 11".

And of course Nagato in 1945 had awesome camouflage!

I really hate to see how so great guns are wasted with no ship to use!

Another plus is easing grind toward Yamato, with remodel placed ~83 lvl.

Give IJN some ship with camouflage (except unrelased SY @ 100 lvl....)
