Improving large calibre main guns seems to be a good idea for you. Though upgrading the 16" gun or Proto 41cm Tripple guns are expensive on 41cm Twin Guns, which are needed for the improvements of both and you don't seem to have prepared a stock of them for upgrading those guns. Also upgrading some of the 35.6cm guns to Proto 35.6cm guns and upgrading those Protos to get some sets of better guns for Kongou-class and others who can't carry larger calibre guns without penalty.

Alternatively you can go for the 61cm quad oxy late model torp. That one is really easy to upgrade compared to 41cm guns because some of those common DDs give 61cm quads as base equip and Kitakami/Ooi each give 2 quad oxy torps (which are needed from +6 up) at their first remodel at level 10.
