I think I'll start it today or tomorrow. Right now I'm in the middle of re-reading all of Justice League International after pushing through Legends (which is so outdated at this point as to be almost unreadable) and am having much more fun with it than I'd remembered.
Omega Men is next on my list, thanks to your great reminder.
I love Grant Morrison, though sometimes I find @Rikdad's amazing blog posts to be the key I need to unlock the fullness of the stories. If you love Morrison I can't recommend Rikdad's posts about Final Crisis enough. No matter how much you might feel you got everything Morrison was serving I can almost guarantee Rikdad's posts on Final Crisis will make the story even richer for you. There will be stuff in there you hadn't considered and nobody had considered or I'm fairly certain that's so. Here's a link to his first Final Crisis blog post but as they go on they get more and more enlightening. Can't recommend them enough.

And of course I LOVED Multiversity and can't wait for the 'sequel.'
I recently re-read all of Morrison's Batman run (like all of it) up to the middle of Batman Inc. which I still have open and am sort of finishing it up in parallel with JLI.
