It might be a good idea to get some guns for CL in case of a combined fleet map, either 15.5cm main guns or Agano-class main guns. 15.5cm guns are easier to upgrade, as they only require copies of the same gun from +7 and onwards. CA guns might also be a good idea to upgrade, either 20cm (no.2) or (no.3), take your pick.

AP Shells is another suggestion, but as you already seem to have quite a few upgraded BB guns around, I don't think it is necessary.
