i don't know anything about backend stuff, but I am planning to look into whether you could create a faux relay that converts nostr data to twitter api calls. seems possible but will be a while until I can actually dig into it haha. I think media integration is more important.

The opposite direction should be doable, there was a twitter -> activitypub crossposter for mastodon. I guess the issue would be exposing your private key to such a service...
I know nothing tech. but just thought if can download new twitter post to local instantly and forwarding to nostr, as your nostrbot does to your lightning node msg :)
For now, you could create a rss feed of your twitter, already ones out there. then run the rssrelay. I'm sure a service that does that will be useful (part of my plan/wishlist). then anyone you want to read (but not interact with) will show up.
yikes exposing private key is no go. I was imagining you would just need a twitter auth token or something. *imagining* being the key word lol
