IMO he needs both hands to execute that barrier T/S jutsu. He held the ftg marked kunai between both his hands. Gakure had a good idea using Naruto's superior chakra cloak to extend and grab each bijuudama while Minato teleports them. How are they gonna break Juubito's six sided barrier is a greater question.
Since Obito can't use his MS to evade and escape I am guessing a super powered RS will be needed. It should hopefully immobilize Obito enough since it's on a cellular level. Either Hashi or Minato will place a seal on Obito.
