I recently had this idea for a Jazz/Hip-Hop band (Jazz-Hop?

) and I was wondering if anyone had tried this kind of thing before and what peoples reactions were to it being played live at bars/clubs.
Something along the lines of this:

Line-up would be bass, drums, keyboard (if we can find a competent jazz pianist), and potentially a dj mixing voices/effects over the top to add to the hip-hop side.
I am a bit apprehensive about what I would play on the bass however. I was thinking a hip-hop rhythm along with the drummer but still try to outline the chords as you do in jazz.
Anywho, thoughts/opinions/experiences are welcome.
