Since the floor can intersect with the T-tray beneath the survival cell, it should be possible to turn the T-tray into the inlet, and route a duct through a hollowed out floor section. It would be the only way to fit a sizeable duct through that area, since no bodwork is permitted around the side survival cell ahead of the floor. Trade-off would be altering the shape of the floor to achieve this. That said, note the McLaren and the Alfa Romeo/Sauber this year have a step down in the floor in precisely that area this year, so it's not as though the tunnel entry needs to be maximum height in that area, necessarily.
Another option may be to simply move the sidepot inlet to the front of the floor (below), or near to it at least, if there is some rule governing that shape of the floor front edge that I'm missing. I dub them floorpods.
