couple of ideas, in case you don't get access to an A0 scanner (local copy shop charges quite a lot for one scan)...
With a project I'm working on at the moment, the old maps have been photographed from above rather than scanned. You could scan / snap smaller areas of each map and ask the community to piece them together.
