How to make armor that makes you have 4 legs like a centaur

I'm assuming that it's like the pants or the boots. But I bet you could make like a model of the bottom half of a horse (or just cut off the head from a horse model) and then if you adjust the placement so it makes it look you have the bottom of a horse. And then if you set those pants to the custom model (under advanced settings in create armor)

I don't know how to make the legs move, there might be a way to make a idle animation with the custom model, idk tho
