It already has been replicated

Look up litecoin. Bitcoin has the market right now. It works by everyone in the bitcoin network agreeing that a bitcoin is valid. You can't just create a new bitcoin and introduce it into the market without having more than 50% of everyone in the market agreeing that it's valid.

No one would switch from bitcoin to an exact copy of bitcoin, it would only leave you at a disadvantage since bitcoins are already established.

However litecoin has a different take on things. Go read about it.

I can't believe I'm defending Bitcoin, I'm still worried about a bubble.

Anyway, market choices are good. Take Silver and Gold for example. You might ask, why would anyone use silver when gold exists?
