I see your point, and how the tail rotor it does create the roll. But are you sure about your description of the direction? Does the tail rotor produce a roll around the main rotor hub? If so, wouldn't a tail rotor in a counterclockwise system produce a left roll if it were below the hub and a right roll if it were above the hub? A good example comes from using your description of the low g situation when the tail rotor is above the main rotor hub with the nose down pitch it creates a right roll. The most important question should be, do the developers need to try and implement this in the flight dynamics?
About the hover characteristics, I have a knew way of describing the dynamics. When the helicopter is in a hover, the center of gravity (CG) of the helicopter will hang directly below the main rotor hub. When you change the cyclic position, the main rotor disc will tilt in the desired direction, but the CG will want to hang directly below the main rotor hub. This creates a thrust in the desired direction without a lot of cabin roll. This description is mainly useful in the dynamics of small inputs during a hover.
