I was researching for more theories and someone made a much more logical theory on the mystery of Stan's identity.

He simply says that Stanford isn't the twin that Dipper and Mabel were sent to and the Author was the intended guardian because The parents of Dipper and Mabel refused to talk about Stanford since he was in a columbian prison but didn't have a picture of the two twins because Stanley and Stanford had a falling out.

Stanford escaped the prison and faked his death to prevent the authorities from hunting him then took several identity's in order to travel to Gravity Falls without police attention so he reluctantly stayed with Stanley as a place to stay until he lost police attention but when Stanley was trapped in the other dimension. Stanford took his identity to prevent people from panicing or getting police attention then worked on saving Stanley but the events of the series delayed him.

In my opinion this is a more logical reason than my clone theory.
