How do would I get聽Collector Chitin Armor, Blood Dragon Armor, and Terminus Armor on Mass effect 2 xbox 360?

I was just wondering if it is possible to get those armors on xbox 360How do would I get聽Collector Chitin Armor, Blood Dragon Armor, and Terminus Armor on Mass effect 2 xbox 360?
The Collector armor was for getting the Collector's edition of ME2. The Blood Dragon Armor was for preordering Dragon Age Origins (got a code for a similar set of armor in both games). The Terminus Armor was for preordering ME2 from Gamestop.



Edit: Again, "So far there are no signs of releasing any of these as stand-alone downloads that can be gotten by anybody. Though if you look around online, perhaps someone is selling the codes to various armors."
