Even if CBP were willing, it's hard to imagine pier 3 being used. It was never set up for customs preclearance, which requires a lot more space than was needed for immigration preclearance. The cost of reconfiguring to simply satisfy extra peak season demand would never justify it.
It's much more likely that other T2 flights would be moved over to pier 3, or a few pier 3 arrivals towed to pier 4 for departure.
