What you’re doing is filtering out bots that can’t be bothered to execute JavaScript. You don’t need to do a computational heavy PoW task to do that.
Most bots and scrapers from what I’ve seen already are using (headless) full browsers, and hence are executing javascript, so I think anything that slows them down or increases their cost can reduce the traffic they bring.
Canvas fingerprinting filters out bots better than PoW
Source? I strongly disagree, and it’s not hard to change your browser characteristics to get a new canvas fingerprint every time, some browsers like firefox even have built-in options for it.

That’s not going to be the majority of your bot traffic by a long shot because it doesn’t scale like using basic HTTP requests.
This is from personal experience. With PoW you just need any puppetted browser, maybe less. With Canvas finerprinting you need a heavily customized scraping browser, either one you made yourself or one you’re paying for. If that’s the case the cost of PoW is neglible. If you still want actual stats, I’d have to ask where you’re getting any stats on PoW working.
