I actually tried it on a VM a few months back, it was broken in a multitude of fun ways. I think it would be interesting to try and make it work.

There is a very nice blog post about someone explaining how they modified their website's CSS to work with some old browser, maybe Netscape, maybe something else, it was well written and fun to follow, but I cannot for the life of me remember where it was from. Maybe someone will read this comment and know what blog post I'm talking about.
