Just to make sure you won't waste time.
Making a mod takes alot of time, before you are done. L'Aigle will most likely be out, also M&B Bannerlord is coming out this year I think/hope. And, there are tons of other mods in progress and coming out.
Basicly, if you make a mod for NW, there is a big chance nobody will play it during the fact there are tons of other mods coming out and allot of guys will swap to L'Aigle and M&B Bannerlord.
So if you do it, I hope you won't waste your time
