Looks good fixed. Why don't you go DA fixed? DA chainset and brakes (I'd have front and rear for aesthetics, headset, pedals, front hub, stem and seatpost would all be nice stick an Eno on the rear and you're done.
You can get an eccentric BB but it will only work with external bearing chainsets - Excentriker and Forward Components - but the cost is approaching that of an ENO hub. I have both on different bikes and they both work well. The ENO hub will be more in keeping with the frame.
