Can you give me some tips on this?

What I am trying to do is create a vista/server dvd that has most vista and server editions all one dvd. What I am looking to include is Business, Home Premium, Ultimate, Enterprise, Standard Server, Enteprise Server, and Datacenter Server. I am wanting to put all the x86 and x64 versions all on one disc, I dont want any of the Core server stuff because it has no real gui, I dont want to include the N versions or Basic Version of Vista. Will all of this fit on a dvd-5 disc with maximum compression? Is there an option when exporting the images so that they dont encode the same files twice so that I can reduce the size of the image even more?
