Seems like not many replies to this, but ill put it out there. I have started the process. I have been in touch with theStoneFox. They are pretty hands off about it, as they don't know anything about playmaker. That being said, I started creating actions for VRTK.
The issue is VRTK changes ALOT, and therefore actions can break pretty fast. Their github version vs the asset store version is not usually the same.
Here is my github which i just started. Hopefully over the next few weeks it should get more actions. I am doing the pointers first.
