If possible, I am interested in a way to configure adding/removing animals or other mobs that can be hooked up to the cart and wagon, allowing for use in other dimensions or when there are mount alternatives, such as Chocobos from Chococraft 3, the Galagas and Monks from Misty World, or Ostriches from Mo'Creatures. Specifically animals or mobs that can be mounted and ridden with just a saddle, without the need for " on a stick" items to direct them.

I feel this would give both the cart and wagon more uses, especially in other dimensions where horses would either struggle or simply cannot reach/exist, or offering options in packs where there are larger varieties of animals to use and where traveling extreme distances for a single horse or animal isn't feasible.
