I have 2 xbox's in the house with 4 players and would like to hook the accounts on both consoles using this family pack deal. One of the accounts already has a Gold subscription (3 months left). I'm just wondering; can this be done? Also, can all 4 accounts be registered on both consoles and switch back and forth when needed? Also, if I buy a DLC on one account, will all accounts receive it? Will both consoles receive it if the account is registered on both?
