I've been kicking around the idea for a while of using the disk images of classic games as datasources for remakes of those games. Games must have databases on the disks that layout things like towns and dungeons, npc dialogue, quest parameters, platform levels, etc. If those regions could be identified in the disk images, read as data, and then used to drive a modern game engine, it could be interesting. SCUMMVM does a very similar thing, reading the original data (usually from files, instead of disk images) and rendering the graphics and sound on modern platforms.
Thought? Crazy? Not worth it? Amazing idea?
