Nagato can't use Limbo probably because the Rinnegan wasn't originally his and thus, can't use the full extent of its power. The Rinnegan isn't preventing Pain's paths from using their jutsu, rather that's just Nagato's fighting style. Obito also adopted his style for a short time but then modified it to his own liking when he made his six paths out of Jinchuuriki. They kept their own original jutsu while benefiting from the Sharingan AND the Rinnegan. Nagato doesnt need king of hell to heal his real body when he can (and has) use the Preta Path ability to restore his body.
