Sneak "crawl" animation mod? (non-replacer)

[YouDoNotKnowMyName]

Good evening everybody.

 

I hope that I am posting this in the right section (it isn't really a mod request ...)

 

Does anybody know of a mod that lets you crawl on the ground while sneaking but doesn't replace the original sneak animation?

 

 

So for example, you press the normal "sneak" key and you sneak normally. You press another key and you crawl.

 

I have searched a bit, but the the only mod that I found only supports 2 or 3 weapons ( and no vanilla weapons).

 

 

 

If anybody knows about such a mod, let me know here.
