HashCash would have some benefits, even if only a few people start using it, and would give incentives to participate: Just don't use it for a binary decision, but as one factor in your probabilistic spam filtering. And make the filter also discriminate on the amount of work put into the hash.

Spam filtering is already 99.x% effective. So you're basically increasing the cost for everyone in order to gain one extra SpamAssassin rule?
There are plenty of reasons why "Payment" anti-spam methods have been soundly debunked over the years. You're not the first one to think it's a good idea, and you probably won't be the last, but do the research yourself first into why they can't work.
