Just a heads up that there were already 2 SocialCG meetups that had possible cooperation between Solid and ActivityPub (Fediverse) on the agenda, but there wasn’t anyone to represent Solid.

No, I do not think so… an ActivityPub conference is being organized and that is what this entails (corona also being the party pooper).
One great way to let Solid community know about relevant upcoming events is to submit a pull request to the newsletter This Month in Solid https://github.com/solid/solidproject.org/blob/staging/_posts/newsletter/next.md
