He will whittle them down to the point that only the Deva path isn't being repaired, then end up killing him.
And he's meanwhile taking a lot of damage, might be trapped in Deva's sphere, hurt bad by a big gravity push, might get chakra drain at some point, has to deal with a lot of summons, etc. etc.. He's getting worn down and hurt in return, you know.
I'm saying Pain's combined power is strong enough to prevent that from happening, he's got a lot of dangerous attacks KB will have to deal with, it won't just be him tearing through bodies.
Pain's overall lasting power is extreme too. You seem to also be severely overestimating repair times. 'The point that only the Deva path isn't being repaired,'? It took 5~ seconds to repair Asura, turn around for fixing a 'killed' path is very short. Trying to outdo the repair rate is suicidal, the only real option is trying to take out the heal path or KB's flat out doomed. He probably will get to heal path sooner or later, but with Deva path in the way, it will not be easy and he'll take a lot of lumps trying.
Transforming into 8-tails is not a sure win, Pain is without a doubt dangerous to do major damage to him in that state. Asura can inflict damage to him physically (big chakra laser or blades or missiles), Animal can send summons to attack, and Deva can smush him or sphere him.
Unless your saying the Eight tails' menacing ball is weaker than What naruto used.
Naruto didn't win the fight, so it could be stronger and still not win it for KB. Raw power of a jutsu isn't all that wins fights.... and Deva Pain's city busting push has more power than either.
Plus even if he charges up for one, that's not a guarantee that it'll hit, that he won't be hit first (gravity blast has a shorter charge time), Preta won't absorb it, Animal won't summon the others out of the way, etc..
