Cryptocurrency could be used here to both decentralize and incentivize such a system. I think a major hurdle would be the fact torrents have been "free" since their inception. PoS is irrelevant here - it's a mechanism that lives "higher up" to protect the entire cryptocurrency ecosystem. Then there's also the social issues and useability issues that plague the space.
My best guess is most bittorrent enthusiasts (and myself) would like to see a more natural solution to the decentralization problem. "Natural" being incentives which arise around sharing / not sharing and similar, vs straight up money incentives.
A reputation system could work but again, Sybil attacks could happen. So some how the network needs to figure out a way to make certain actions more expensive in the large.
