As I said, I'd use it with a Bb (the previous post was supposed to read "Bb" not "B") or E in the bass. So it'd actually be a root-less "BbMaj9 #13" or "E7aug b9/b13". There are some nasty sounding chords that I've heard Joe Sample, Russel Ferrente, Jeff Lorber, Alex Bugnon, and Herbie Hancock do, I would guess this would fall into that category. Even some of the crazy chords that John Peters does on his new DVD would fall into this category.
I'm not very proficient at using these yet, but I can try to post something. I have a couple others that I use though. It was almost 3am when I answered this post, so I didn't post anything. I've found that when you play out of key, it can sound like you're doing some very dissonant (complex) stuff and you're not.
Here's a post I did around this time last year.
