Hurtworld Floating / random rigidbody movement and rotation

I need to sort of some textures and such, but I'll soon have a modular mesh object of iceflakes with colliders, and some effects hardbaked, such as wetness (dampness).

I want to try and attach a script that deals with interaction of player or vehicle on these sub-objects. Creating the effect of ice sinking. Or at very least make them "wobble" slowly. Adding realsim and gameplay to it.
If I understand the new SDK update correctly, this can be done now?

- Team effort?
