If I may make a suggestion, or rather, more of a request hehIt is within the possibilities yes.
Why not make so the mod works perfectly with one of the fixed branches of the game? say 1.5.9, that way people that want to keep playing this mod can just pick that particular branch and not worry about any future patches without you having to constantly fix it.
perhaps wait till they bring 1.5.10 up to stable(and keep it compatible with 1.5.9).
Either way, I understand your frustration, they're really dropping the ball here in a huge way, modding is what made warband as big as it is, instead of doubling down on that they seem to be trying to nerf it...
