Well, the first SAE carriers where cruiser or BC hulls with hangars and flight decks attached like superstructure. With the light fleet carriers of the Anvil the hulls were patched up first time as protection against the elements but armor had to be ditched. With the Thomas van Deen armor returned while the patched up hull remained - though I still considere hangar and flight deck as superstructure.
Next in the line, and first drawing missing, is Michel Endress. A purpose built training carrier of limited size I think the design philosophy would be kept to keep the design easy. Probably she would also show the return of the open bow, although not as open as on the Forge. More like on IJN Hiryu but with her bridge on the right side and a vertical stack. The look of IJN Hiyo also might be an option. But I am uncertain. She could also be designed along the lines of Anvil, a bit like OTL british Collossus. Her main guns are meeant to be fore and aft of her super structure.
Then came Asgard and with her the use of the british design philosophy - hangar and flight deck as integrated part of the hull, Implacable style.
Helspanth ought to be similar, though smaller while Bahamuth builds on the experience with the earlier classes.
Historical carrier design I like for their look in addition to the ones mentioned above are IJN Taiho, HMS Unicorn and IJN Unryu . the later for open bow designs but with a vertical stack.
Hope this helps. But please, don t feel hard pressed to do it exactly like I proposed. If it were so simple I probably had done those drawings already. :o)
