You use large transom stern, I was under the impression that this is sth used on modern merchant ships and supercarriers, while what was used in WWII time period on US ships was small transom.
I think that for successful operations surface raider needs guns heavier than typical cruiser. Not because you want to fight cruisers - you don't. But a balanced cruiser ship with 5-6in guns wouldn't, IMHO, provoke the same response as similar ship with, say, 11in guns. Against 5-6in ship, only cruisers would be despatched, while 11in ship would force all fleet assets available to take part in a search. Not because it is objectively stronger, but for psychological reasons: Deutchlands, big gun CAs, were, and still are called "pocket battleship" while Baltimores, bigger and better armoured are forever just plain CAs and even bigger Worchesters are CLs...
My take on the subject, 10in guns to scare enemy press, good AA to scare bombers, mines for additional attack vector and 4 floatplane fighters for scouting and chasing enemy long range planes.
