I don't think that would accomplish much. People would just delete the 9 papers that they don't care about rather than maintain them as clutter. And even if everyone did keep the extra files, would use would they be? It would be impossibly difficult to reconstruct the archive from them. It would probably be better to break down the torrents into smaller, more coherent, and organized collections that contain all associated metadata (e.g. a collection of biology papers from a certain time-span or set of publications). That way you might incentivize people to maintain smaller personal-use archives that could be recombined back into the whole, if the need arises. You could perhaps even build a system that could automatically generate, publish, and consume torrents with a particular (metadata + content) layout, but that's not restricted to a particular set of torrents. Then it could just consume certain topics from a feed of new torrents, from various sources, on the Pirate Bay.
