You can technically make it work with Warband : https://forums.taleworlds.com/index.php/topic,321424.0.html
But it isn't intended to work this way, and doing so isn't supported by the mod's creator. There will be glitches and error messages.
Anyway, doing it requires to pick a file from the original M&B to paste it in the mod's folder, so you won't be able to do it if you do'nt already own the original M&B.
