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 like summoning back ninja tools, and 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 rearmost 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.
