You could... but it's singly not setup for that. There are blog softwares out there that support activitypub-- I have no experience with it, but microblog.pub was nativity designed as an activitypub blog. There's also a WordPress plugin that's basically official (maintained by the company that owns WordPress.com) and has known good integration to at least mastodon, so I would assume it works well with lemmy, peertube, etc, since AFAICT, mastodon is the most opinionated of them when it comes to activitypub conformance.
