An official Bloodborne PlayStation 5 60 FPS patch is now possible, according to the developer of the unofficial patch released a few months back.

Speaking on Twitter, Lance McDonald revealed that Sony is somehow enabling games compiled on old SDKs to detect that they are running on PlayStation 5 and unlock the frame rate. This is what happened for the recently released Ratchet & Clank PlayStation 5 update.
