This is a good idea. The activity pub protocol was based on an idea like this tranlating email (specifically inbox and outbox) to http. That is now a decentralized network used by 10m-100m users. And there is even a bridge to nostr. Since nostr is already a subset of http, so could do it already. A specific version transmitted over relays could work too. Most of the work is done there.
