Is there a easier/better way to do this now than originally explained in this post?
Replace S-Voice with Google Now (Home button double tap)

There is also a new issue, is it possible to change the screen off voice activation "Hi Galaxy" to launch Google Now instead?
I am using a Nova Launcher and I configured a single press on the Home button (when on main screen) to bring up Google Now. Works great.
Exactly what I did as well. Just wish I had a way to make it go there from any screen instead of just the main screen, but that's a minor quibble.
