You can probably run i3 in X11, although non-X11 apps won't work with it. Your best bet is to run i3 in a full-screen VM.
I researched this myself a few months back, since i3 was the biggest thing I missed when I had to switch to OS X (new company, new computer). Eventually I gave up and settled on Amethyst. It's not bad once you set up the keyboard shortcuts to your liking. The main things I miss are the tree structure for window organization, and window borders that stick together when resized.
I created some bounties on bountysource for features I'd like to see in this project. Hopefully other people want them enough to contribute as well, and ianyh will get a nice return on his contributions.
