Not really sure what you're getting at...you want to take a three dimensional object, the wing, and replace it with a two dimensional object to look like a three dimensional object? You'd need a shadow box, build the feselage and attach it to the back then paint a forshortened wing on the glass cover. This would ony work in level flight, sine you need to paint the other wing, with propoer perspective onto the back drop.
Also, I don't think anyone can copyright (or patent) gluing half a model to a mirror so you are completely free to do so. Heck, Shep Paine was using mirrors in his dios 35 years ago and the use of mirrors as part of an optical illusion is so old, it has it's own idiomatic expression: "It's all smoke and mirrors." If you do this, however, remember anything you see in the mirror will be reversed and US aircraft have different marking on the upper and lower of each wing.
