After the discovery of the speed of light, it may have made a bit of sense to redefine the meter as [itex]\frac{1}{300,000,000}[/itex] the distance light travels in a second. I understand that larger units like the light year may have been distorted a bit, and that conversions would be required for such areas, or others where precise measurement may have been required. But my point is that the current SI system is a bit arbitrary(fortunately less so than the so-called "customary" system) and using the speed of light in a vacuum would base it upon a universal constant, not something that can easily change.
