We've seen P.T. PS4 Model Data & Textures, Final Fantasy XV Character Object Models, Fate / Extella: The Umbral Star work in progress, Tomb Raider: Definitive Edition PS4 / PC Asset Conversion and following his Swizzled PS4 Textures Bloodborne research on Github alongside PS4 Havok Files testing developer @SanadskYoutube has made available BBAnimConverter which will currently convert Bloodborne and Dark Souls 3 PS4 game animations to HavokTools-friendly files for modders. 
Download: BBAnimConverter.exe / BBAnimConverter-master.zip / GIT
Going by Sanadsk on Twitter, he also hosts a popular YouTube Channel to document his research and data mining game assets including PS4 titles such as Shadow of the Colossus below.
Here's more details from the README.md, as follows: BBAnimConverter
Tool Description
The hkx animation files of Bloodborne cannot be opened directly with Havok's Tools, and that's because they are formatted for PS4 use. This tool fixes these animations so that they can be previewed in Havok's Tools.
Usage
Run the program, and Choose the folder you have the HKX files in (The program creates a folder called "Place_HKX_Here", which you can place your files there as well). The result files will be in the "Output" folder created in the same folder the HKX files are in. The files can be opened now with Havok Tools 2014 64-bit. You need to load both the Skeleton.hkx and the animation file together to preview.
