Using Online Password Cracking??

Hello , i want to ask about something , when we are into getting for an example a victim , i know his/her name , phone number , boy/girlfriend's name , date of birth , which all is a possible passwords or a part of it , is it possible to find a script that can do that for facebook for an example i give the script data about the victim and the script try tons of combination to find the password ( without making facebook delete/block the account from anyone logging in , not to make it suspicious ) since facebook.py and stuff like that is a dead end with a problem i guess ?

so is it possible ? if so , anyone want to work on such a project ? and is it possible to use on email of the facebook which can be (yahoo/gmail/hotmail ) , cause that would make a great step into hacking the accounts of the victim.
