Don't answer if you don't have a proper answer.
Now on topic,
Yes, that is possible. There are title updates packages floating on the internet, connect your HDD trough a kit or trough a simple sata connection with your computer, transfer the files inside the package to the HDD (the package contains instructions) with Xplorer360 and boom! You don't have to worry, Title updates are not constrained to one's gamertag.
You cannot transfer your XBL Arcade games, unless you have Jtagged your console.
