Who exactly would use this product?
You'd have to be someone who doesn't mind ads, but doesn't like bad ones, while also being someone who is willing to pay for content so you do not see ads.
More to the point, in what possible universe is there a moral justification for stripping a publisher of the advertising they've selected, only to replace it with your own, and then dictating to the publisher what percentage of that revenue they deserve?
If you care about users, just strip out ads. Don't replace them.
If you care about publisher's getting paid, just establish a mechanism that makes it easy for people to stick a META tag in their header which shows a Bitcoin address for payment remittance.
Publisher's can then implement a mechanism to verify whether individual users have paid.
If your project needs to make a profit, either charge for the browser or the service which intelligently strips out ads, the way Tivo charges for their "Guide" feature.
This is a convoluted business model which helps literally no one other than Brave.
