I haven't seen that anywhere. I have a Hornady that I converted to flipping bullets MBF style, then from that point you could make a slide to do it I'm sure. But you'll be the pioneer.
I did make one that works well from AmmoMikes small bullet feeder bucket, but it required a special plate design and an upper baffle to keep bullets on their sides.....made for my Lee APP.
Below is my modified Hornady flipping bullets base down.....point down would require a different shape at the top to flip them backwards.
