If I were to suggest a solution, it would be modeling by parts. Model the engine nacelles via a revolve operation, they are cylindrically uniform, after all. Then model the wings as an airfoil and extrude them out. I'd assume the foil is of constant section geometry, the scale is the only thing that varies. Merge that wing together with the fuselage, and then blend the rough parts, then merge the nacelles and the wing - and you may not even need to do that! In the end, flat quads and nice edge loops will do much to solving many of your lighting troubles.
