I really wouldn't bother releasing an exact copy it just seems pointless and has already been done before. Maybe look at something different or at least changing the supply or algo.
for me you can create but how you fund it! may be you just curious on how bitcoin are made and coded!
just try it for experimental used only if it success and you can fund it by yourself or help of other rich man just name your coin just like other cryptocurrencies.
good luck.
