The damage that Nagato received from the Gedo Mazo appears to be irreversible, otherwise he would have healed himself, Pain would literally not exist, and Nagato would just wreck house by himself.

If single body healthy Nagato and Konan went to invade the Leaf, it would be GG. Kabuto never said he wasn't completely healed. he simply said that he had a lack of mobility. most likely because of the fact that he hadn't moved his legs in years. despite a lack of mobility he still moved quite well
