There was something like this going around in ~2008, it was a plugin bar that turned the internet into a game, you could leave mines and portals on websites that would take you to other websites, so people could add their own hyperlink layer on top of the internet.

I wish I could remember the name of it, I played with it for a few weeks but then they put up a paywall.

That spirit of communal being-on-the-internet I only saw breifly recaptured again by the Beaker Browser, which unfortuantely seems also to be going the way of all things. There you could fork and remix any website you were on, could in principle afford a much more mucking-in stle of what you are trying to do here.

I think this could be great! Keep at it!
