Question for theoretical mobile setup

Lets say I have an iPhone running DJay Pro. Connected to that is the camera connection kit (http://www.apple.com/shop/product/MK0…)
A USB hub is connected to the CCK. Off the hub is a Faderfox controller and an NI Audio 2 mk2 external soundcard.

Would this setup allow me to precue off the Audio 2, and let the Faderfox send commands, all through a single lightning port?

I tried this setup and it works great.
