Add-on to reverse youtube handles system

We already have return dislikes extension that fights against bad YouTube interface changes. Now we need to somehow revert the controversial channel @ “handles” in the comment section user names. I don’t even know if its technically possible.

The idea is, for extension to somehow identify all the user names, follow the link, grab the actual channel name and replace the handle with it. Can this be done?

For now, the only thing I can do is to just remove the usernames altogether via CSS.
