I've had one in mind that I haven't had time to get to, and may never, so I don't mind revealing that my plan was to have it look as though Thanos is reaching around and through the right side of the cabinet (possibly looking as though he's breaking through the wood), with a slightly larger (and of course more detailed) glove gripping over the right ramp, so the ball goes under the palm, and with the stones/glove still angled in a way to be visible by the player.

Perhaps I'll get to it one day, or someone else will come out with an interesting upgrade. Otherwise, Steve's paint is certainly better than the dish washing glove.
