Add Lemmy-equivalent communities to the sidebar of archived subs?

For example, it'd be nice for anyone that looks at/finds https://lemmit.online/c/dota2 to also find that https://discuss.tchncs.de/c/dota2 or https://lemmy.world/c/dota2 is an actual community that corresponds to that with user content, not bot content.

I'm sure there's lots of equivalents for other communities as well where that would make sense.
