Yes mate!
Bitcoin Development Team ain't weaker than Ethereum Team as Bitcoin is open source, as long as you can make sure 51% of miner agree with your idea. You are good to go.
But IMO, Ethereum serves more purpose than just a currency, with the help of smart contracts, alot of things can be done with it
I agree, even tho btc will allways be the first one, eth still has a long way to go, because lots more uses.
