Don't see why Sasuke couldn't open a portal and then swap his opponent with whatever he sees on the other side of the portal when it's as small as the portal Obito and Sakura created. He used his ability to swap with Sakuras jacket when the portal was practically gone.. The portal was clearly too small for a person to walk back through. If the opponent is too far he could pull them in range of his Ameno which I remind you is using swap for increased range. Sasuke was shown using perfect susanoo and Ameno after his eyes were drained so it's surely possible. Deva pull removes possibilities of moving and once they are in range of swap they literally can't counter it. The portal would be too small for his opponent to make it back through. If Sasuke needed too he could always throw his sword through the portal and after he swaps his opponents location with it could walk up to his sword pick it up on his side of the portal and go home.
