It's a good ideal and great work, but over the past decade the same cycle all over again, you simply can't move 36% of the internet into a new platform Just because you think or it's better, as you mention most of WordPress users are no programmer
If you want to move people from WordPress you will need to create a plugin where they click and poof all of their data is moved to a new platform
and The new platform comes with all the most wanted plugins already integrated per default and the ability to customize the front-end
Then you may have a chance.
headless cms maybe.
