I was thinking about it the other day, I don't know if anyone has came up with it yet but if someone has just bare with it 
When Itachi destroyed Shisui's eye telling Naruto that it would be useless unless someone posseses Hashirama's chakra uses it or it will take 10 years for the recharge ( or it's just the 10 years recharge thing?? )..
Now that I think about it Hashirama's chakra = Ashura's chakra = Naruto's chakra..
which means no one but Naruto would have been able to use it and it would be quite BadAss..
Thoughts..
