Been away for a few days so sorry for delay in reply.
I agree with Dave’s thoughts in general.
You do have a lot of internal room to play with.
I know you’re having problems uploading pics but would be good to see more.
My main concern is still the flexing of the deck with all the main superstructure on it.
I fear over time it is inevitable that there will be stress damage.
If would help a great deal with support added directly to the underside of the deck.(I had to adopt this with the flight deck on HMS Victorious)I will find some pictures to post.
Are you going to be motorizing the main armament etc?
I will think further and get back to you when settled in again.
