Can you create a pokemon with his PID?

I'm having a new question, never found response about this. You know pokemon are scripted, and individuals by their PID. My question is: Is it possible to change information with a replacement by a real PID?

Exemple: You got a calm ratata lvl 3. You know the PID of one shiny adamant ratata. If you exchange their PID, the calm ratata could be a 'legit shiny adamant ratata'? Thx. ^^
