Not that im aware of.

Seems buildable. Would you use it? The idea would be to have your Nostr npub contain all of your old tweets. Would not have the same likes etc, but the posts would be there in case you ever wanted to repost or link to them.

Aha yes, exactly this!

If you look at my profile on nostr.band, it says I was first active 5/9/2021 on Nostr. I had no idea what Nostr was then. I created this npub in December of 2023. However, I used exit.pub to upload all my tweet history to Nostr for my account created shortly after I got into Bitcoin.

Yes. Exit.pub by @PABLOF7z

You might consider - before leaving Twitter - communicating there your departure to nostr. Through Tweets, a space or DM? Might get some other good folks over here. 😉
