Why not put the arm on the turret? Now you can grab tubes off whatever side of the robot is handiest, and launch the minibot on whatever side is handiest--and the minibot may act as a partial counterweight to the arm if you do it right.

Full rotational capabilities are tougher--run your wires/tubing up the middle with room to twist a bit, and I think you could do it without a problem. Running up/around the side will give you headaches.
