This is an idea I just had (litterally) so I'm thinking you take the textures of a the Alaska Airlines 737 and make them available except in the 747 & Airbus form.
Also I tried to make a 737 of mine have those textures and now I can't raise or land the landing gear, I can see through the plane, the nose wheel is above the plane, & there is a bar running through the middle of it.
