How would you set it up? The decentralized world doesn't really have a great system for curation at this point (unless you can point to a counterexample!), and so I'm in favor of any sort of playing around with decentralized voting/curation until we find something that seems to be working well.
Start from the objective of first do no harm. Voting systems may eventually be gamed to distort results, so eliminate the voting system. Instead rely on ad-hoc personal networks to disseminate signal about quality papers out-of-band. Don’t assume you have to systematize everything.
Voting (as was bore out in many examples including digg.com and elsewhere) becomes a mob rule situation and variation of tyranny of the commons without a novelty algorithm in addition to total votes. If you just go by totals, it will be easily gamified and rendered useless as a metric.
