Nothing you can't accomplish with sanding, putty, and fabric overlay. 1/32 to 1/16 aircraft ply is really malleable after it sat in your swimmimg pool overnight.
Those old timers were skilled with wood structure

You could never get there with coroplast. 
Howard Hughes made these the same way as the 'Spruce' Goose. aerohead is a fan of reinforced concrete forms.

You are saying the skins are built up in layers? Coroplast does heat soften

The dinghy and this display case are under the wing of the Spruce Goose in the Evergreen museum (last I checked). I don't know the technique, possibly vacuum bagging like carbon fiber. The result is essentially compound curved plywood. No sanding or putty.

The fuselage of the DeHavilland Mosquito was formed from streamed strips of wood and adhesive,laid up inside a concrete mold, with a balloon at the center,which forced all the loose plies against the mold until the glue went off.It made a beautiful,lightweight,composite,compound skin.Very cool!

Clingenpeel told me how they made the Hercules wings, but I was young and didnt pay close attention. I do recall they were built, installed then covered. I suspected a combo of vacuum bagging and sandbags. Really hard to seal the underside.

In OZ they made them on the outside of concrete plugs, then strapped the wood down.
