Awesome to hear! And I do look forward to seeing your take on a battleship carrier
Good luck and I'll be keeping a close eye on the mod.
Also as a side note I've been trying out adding 4 fighter bays to the Relic Super Battleship and 375 OP and it seems to work really well. I'm going to bump the DP cost of it up to 60 and I think that's a pretty darn fantastic ship
A bit op but very fun! XD
Another thing I've noticed looking at the lighter ships, cruisers and down, Mushashi ships tend to be rather badly off compared to most other factions non capitals. With a LOT of cruisers mounting many more and larger weapon mounts mounts. The destroyer is decent but again there's a fair few other DDs in the mod verse and base game that mount a large weapon and other things and frigate wise it's again fairly poorly off.
Admittedly given the form factor of these ships with their center line mounts and such it is harder to come up with layouts that mount a good amount of weapons.
The way I see it this might be just fine considering just how powerful the Capital ships of this pack are but if you want to adjust the non capitals I'd recommend looking into the comparable sizes of ships in WW2
For example in WW2 cruisers and battleships were usually more or less the same length. Just the cruisers were a good bit thinner so they could go faster and mounted lighter weapons and destroyers tended to be about 2/3s the length of cruisers. So taking inspiration from that should let you make some longer but still fairly thin Cruisers and DDs that while very long are fairly accurate to WW2 and should give you plenty of space to put mounts:
And then here are some sample layouts of heavy and light cruisers that might be helpful for setting up some of your own:
And for destroyers you could do something like the Fletcher with 5 centerline small guns, or something similar, and then 2 medium or large missiles to act as torpedos.
Again though don't want to seem like I'm trying to suggest how to make your mod but I figure these ideas might be useful to you?
