OSS is nothing more than making the customs/connection procedure better; your comment is just a tautology.
The terminal seems to have enough physical room to easily drop in a couple of customs stations on the second level behind the DOM side of the hermaphrodite gates (or could if they extend the 2nd floor over the double height customs room) to physically implement OSS. But none of the airport authority published plans I've seen indicate that this is on anyone's radar.
