I've published a finished version of the draft I made above on the Dev Wiki (DarkScrollingGlobalNav) for those interested. I've also made an alternative version, DarkGlobalNav, for those who'd like the global nav to always be dark (looks quite nice!).

Changes from the draft include:
 * fixed hover/active states
 * search box is now also inverse
 * banner notifications don't disappear behind the global navigation bar
