I don't conceive it possible coz I'm a bitcoin admirer as well as its believer, Satoshi is my god and god's intention cannot be changed. provided that someone is here to change the amount of bitcoin, then maybe Satoshi will land and forbid it. Bitcoin is limited and humans won't reach a consensus of enlarging its number. when bitcoin's amount rises, bitcoin is not bitcoin any more 
Anyone can change the codes because now everyone can learn about the blockchain and build their own. But it cannot be the original bitcoin that is what the blockchain and decentralization is about so yeah God is unique.
