Has anyone considered alternatives to the current Système International in their TLs?

For my "For Want of a Nail" (British North America) TL, I'm thinking about defining the International Foot or "Pied du Dieu" as the length light travels in one-billionth of a second (a nanosecond) and defining my International System of Ordinances (Iso) from there.

Anyone have any other ideas?
