Well I only have a 20gb "original" HDD with only like 9Gb space left, so I would hope that I could use my external USB HDD. The problem is that I want to get back to the XBLA -list after I have a played a game, not having to start over every time from the original dash everytime I quit a game. Is that possible?
Dude, this guy just told you how to do it the way you are asking. With this method it will work just like you have replaced your NXE dash with freestyle dash. When you are finished, push the guide and select "play game on disc" and you're back at your XBLA list.

just boot the dash from dvd then when you want to go back to freestyle, push the guide button and select 'play game on disc'
