Well we know the summoning would work, considering Sasuke was able to summon Garuda in one of Kaguya's dimensions, and her space-time jutsu is much stronger than Obito's. As for their connections being severed, assuming that they are, it would be similar to summoning back ninja tools, and the Rinnegan's summoning abilities require no blood, hand seals, or scrolls to be used to complete the summoning, making the summon entirely feasible. Also, Nagato can perform this reverse-summoning himself, in the case that the Animal path is compromised.

If Obito did damage a path until it was no longer fit for battle, that is what the Naraka path is there for. We all know Pain's formation, he keeps the Naraka path in the rear-most position, so he would be guarding it with Deva path for whenever Obito materialises, and with Preta path for Obito's fire and wood style jutsus.

Seeing how high and fast the bird summoning can fly, we have never seen Obito teleport that high into the sky and I highly doubt Obito would be able to catch the Animal path this way, the highest we have seen him teleport if I recall correctly (ignoring geographical altitude) is on a tree against Naruto, Kiba and others, and it could be interpreted that he needs to teleport to a place where he has stable footing, like on the tree branch. It would be useless to teleport into the sky anyways, as once he materialises, he is subject to gravity, and I'm pretty sure Obito can't fly.
