To me the Ox-carts make Babylon MUCH more boring to play due to them being created in TC, so I'd suggest for the sake of making them more smooth and fun to play one of this suggestions/changes: 1) Make Ox-carts possible to build with a villager in open terrain as a regular Storyhouse, with the difference that the finished product is a movable Ox-cart. It can still be manufactured in TC also. 2) Give Babylon a stationary storehouse alternative also, I don't care if it's twice the price. Ox-carts could still be made as usual, this would just be an alternative. Babylon is a nice civ, Ox-carts is a good idea, but the creation in TC just brings the whole civ down to "I almost never play them" for me.
