It works!!!
So I did manage to keep all internal links unbroken, which means "https://8*". KEK, pic related. It's not a perfect solution, but it's close enough. If you see other people linking to other sites with 8 at the beginning after https:// just report it and I'll add it to the filter.

As you can see here, full links will work, as long as they are on 8ch.net. Now you have clickable links to archived posts.
