These were originally released by Skywave - ocassionally you can find the Belleau Wood in a Skywave box. Revell of Germany re-released these under their name as well as Dragon. IIRC, one of them came with a full hull option.
Not sure how much experience you have with photo-etch, but Gold Medal Models makes a light/escort carrier set that includes both early and late-war masts for the Independence class, so you can build just about any ship from the kit .
It builds into a decent model out of the box, but it does have some fit problems, especially when you try and attach the hangar walls to the hull. At least that's the problem I ran into.
