Instead of william wilson killing william wilson mimic, in the ending we created he offers them to work together committing crimes, to be partners and to go further as criminals, the story would be like this ...

It all started when in Moscow the two William Wilson met and the real William had the opportunity to kill the Mimic, but just at that moment, the Mimic offered him an interesting opportunity to become partners in crime. The real wilson liked that idea, so they started the best criminal duo ever seen. Together they did incredible acts that passed to history, but not precisely for being good acts, but instead for being very bad acts, like assaulting the Vatican or demolishing the great Roman coliseum that remained standing since the year 70 BC.
