Without actually seeing what they're using the disc space for it becomes impossible to determine whether a port would be possible. Personally, I doubt that it is 50GB for ingame assets and is probably full of 1080p FMV and a large portion of the rest of the space is probably used for loading time optimization; if I'm correct you could probably load the game onto 2 DVDs simply by reducing the resolution of the FMV.

The space is also being used for CGI movies and uncompressed audio.
