This is generally the layout I have planned out for this part of the level -- yes, I say "this part", I intend to have a short beginning that's just going through the forest
The bottom of the ship will be utilizing highly athletic sections and making use of the cape, mostly in gliding, and the insides/tops will make more use of enemies and artillery an' all that. Super Koopas sound like a good idea for the top
And yeah the idea of the airships being made out of the wood from the forest (it's magical or whatever and lets them fly or whatever) is exactly the kind of thing I was going for.
