Well the BF2 modders have their Middle Ages project going, so why not get one for BF1 going?
I've already had a demo map posted on SWBFfiles, but that was just a demo. If we can get some people with moddling abilities and/or better skinning that mine

that would be nice. Maps can be made with simple retexturing and resizing of existing props, like the tusken tents for camps and the Tatooine walls for castle walls.
If you wish to contribute please post.
