Yes, it would - and the solution might not be quite as simple as one would think. It would require some discussion as to what the best way to implement it would be. The issue that would need a creative, safe, and fair solution would be how to remove existing votes, and which ones to remove.
We would have to reset all votes and then people would have to go back and re-vote for those they want. That would actually be a good thing as there are some dormant votes on there that likely don't need to be. The more I think about this, the more I think something in the 5 vote range would be ideal.
But yes, we would need to make sure the chain continues running while the unvote/re-voting process takes place... for that perhaps we just keep the same top 20 in there for the first 24-48 hours until there has been some time for votes to be recast and a new top 20 set?
