I've done a few planes with transparent.. though mostly it's a mix of trans and opaque..
I'd do the LE and TE of the wings in Opaque with the ribs transparent.
The fuse was almost always opaque unless it had some open framework to show off.
My friend Harland had a Yardstick (about 8ft span) that was done in Trans Green and Yellow. You couldn't loose that big slow thing though
