I’ve asked about this, myself. However, as far as adapters for EVA1 handgrip bayonets to Arri rosettes go, Wooden Camera is releasing one pretty soon.
Several manufacturers have this adapter now. That way the Panasonic handgrip integrates into existing arm extensions. I have not seen any examples of an arm to mount directly to the camera or an Arri rosette adapter for the camera's handgrip mount. Note that it was not designed for such torque force, so I don't know if such a thing is a good idea. Not saying it wouldn't be perfectly fine, just saying I don't know.
