I doubt the early WT thought Papias had much to say when the subject came to the transformation of the Earth in to a Paradise. There's some strange things he claims he heard by close associates with JC, Bart Erhman has up on his paid blog more information about this topic. The basics are that Papias claimed Jesus said "The Earth will sprout so much food" that those gigantic cluster of grapes brought in by Joshua and Caleb are nothing compared to what's in store for followers of JC. Papias claimed the early followers of Jesus taught we all would live on Earth with new bodies to enjoy all good things it has to offer.
Eusebius doubted Jesus said this and thought those words might be a forgery, maybe the JWs are on to something? Bart also mentions he got a tour of St. Catherines and felt pieces of the Codex Siniatucus in his own hands, check out his blog if you have any time. I post and leave the rest up for you to decide, it's all interesting stuff!
