They've already done this...
Many "crossovers" (which are just hatchback sedans with lift kits) are being classified as "light trucks" to both improve their passenger car average (by removing the less efficient vehicles from that spectrum), and improve their light truck average (as they are "ringers" in the truck mpg category). Additionally, cars have been getting slightly longer and wider on average, as increasing this footprint gives them the same gov't break as actually increasing the fuel economy, but is much easier to do.
A classic example of this is the PT Cruiser (which is just a 4 door Neon hatchback with some "retro" styling cues) is being classified as a light truck.
