I don't think any wireless flash control will do TTL-BL, I think it would be just TTL. With careful picking of aperture, shutter speed, and ISO you could probably get the balance you need.
Because your flash is only a short distance from your camera you could use a corded connection instead. Nikon sells the SC-28 and SC-29 hot shoe extension cords. There is also the out of production SC-17. All these cords allow the flash to function as if it were in the hot shoe.
