Ok finally found it and it doesn't seem as simple as was explained. They are the same standard, but it isn't hashed to the same size, which just looking at it should've triggered to me that it was longer than a normal address just by character count. However it does seem to be the case that you can generate taproot addresses from the nsec and/or use your bitcoin wallet to also generate a Nostr ID with relative ease. But the degree of connection i posted above doesn't seem to check out in practice. 

Post that was suggesting the beginning could just be swapped, when it seems like it needs to be hashed differently, but the rest of the description of it seems to be correct:

A post discussing the differences and how to generate addresses or npubs from each other:

 Yeah. If that were as clean cut as initially thought. That would be incredible! Even the ability to take an existing wallet and somehow convert that to an npub would be incredible so that organizations and institutions that had a wallet could have a public identity and you could verify the wallet with the identity or vice versa. 

 Yes, I over simplified, apologies.  You need a checksum too.  Though I dont even think the checksum is used.
