Help blending body texture seams

[Nots5]

Hi, I'm trying to edit the textures from the Satyress mod, blending them with The Pure CBBE. It's for personal use, given I prefer the idea of a more human-like character rather than full on furry. Yet, there's always the same problem:

 

 

I can't seem to even aleviate that seam problem. I'm completely new to modding, so maybe I don't 100% understand how the "wrap-up" of the texture works. I'll attach the texture as well. If someone could point out how could I fix it, I'd appreciate it greatly.

 

Thank you.

 

PS: I know the edited .dds looks like an absolute mess, yet it's for personal use and it mostly works. Even "clean", the seam problem persists.
