Scripted/Software binds and Vive input hijack

Greetings
Basically i want to implement a software/script method to emulate VIVE controller buttons. I have NO idea how to do that with new updated SteamVR plugin. Dug as deep as i could but with no success
For example some script overrides actual grip button and makes a character close his fist.
I was trying to find and intercept Input values from the controller so all other scripts (like ones that transform hand bones and process grabbing stuff) would not need any modification but...

I also thought that i could somehow make additional software bindings to an existing default controller action sets (which would basically simulate IRL buttons) but haven't found a way to do that. Maybe i should somehow create a software controller, i dont know.
If it worked then it would expand some modding boundaries. It would be the best solution imaginable.
Any thoughts?
Thanks in advance
