Would love this also, looking for a card with similar functionality to the Google Home ChromeCast volume sliders.

Thank you for the request.
I will start our by saying, I don't even know how to start implementing something like this in the slider-v2 because all the math calculating the position of the slider and the actual value for the entity, relies upon X/Y values compared to start/end of the slider.
Making it round like this would require some serious refactoring in the slider-v2 and I just don't think it would be possible without breaking a ton of other logic.
It would probably be possible in the original slider. Since it relies on the HTML input slider element. But I don't know if I will ever have the time to implement it in that. When I finally do get time to update the cards, it will be to address some of all the problems regarding HACS.
