I actually don't use the Four Legged technique anymore, I haven't for years since I have my own replacement for it.
I do like the lore that you've dropped though, and I understand the basis behind the style.
Essentially, it's pushing further into the realm of the Beast, faster, stronger, more wild and, resultingly, more lethal. For others this would result in a stronger Four Legged Technique, for me it means my Fenrir's Lesser would be great I guess.
But more importantly, it allows for a unique style of Taijutsu which essentially exists as a more bestial version of StrongFist.
It's this that I'm interested, mainly because I have a couple ideas for offensive attacks that, I felt, wouldn't quite fit as a basic Inuzuka technique, but would definitely have a place under this style.
