To see one method that is used to work around this sort of thing: The folks over at http://www.tlmc.eu/ have been expanding the same 1.2TB collection of files for a while, just by stopping the old torrent, running a Python script to patch the changes, and then rechecking and starting the new torrent from the old directory.

but doesn't this mean that all the other peers would need to manually upgrade their copy of the torrent file?

Yes. It works reasonably well in this specific case because it's such a niche thing (you don't download 1.25 TB of Touhou music if you don't really care about Touhou music), but it doesn't benefit from people who continue to seed things they've long forgotten about.
