Nagato can summon them, as he has all 7 Paths abilities including Animal Paths. So whether he can feel their chakra or not he can summon the bodies. The whole him being able to summon them wasn't really explored upon until Naruto vs Pain though. So Obito could warp them but they would just be summoned back to Nagato. Also Barrier: Toad Gourd Prison is classified as Ninjutsu, Barrier Ninjutsu, Space–Time Ninjutsu, it is definitely a different dimension considering that the Path and Jiraiya's chakra signature completely disappear too.
