Yes I'd be up for something nice and simple, ideally with an option for blank or at least windows-less bottom row (as would probably be all Mac users).
I'm using mainly Windows nowadays but my bottom row is remapped to this (from left to right) - mostly because I spent last 10 years using OS X as a primary OS:
Caps Lock, AltGr, Alt, Space, Windows, AltGr, Menu, Right Ctrl
