Maybe you could borrow some stuff from the Deluge mod. It was a really cool mod. I just never experienced anyonne playing it.
The face creator from that mod was really good aswell!
Deluge is the best Warband Mod imo
It´s a pitty that you never played it in an event. They were awesome, we did those Tercio warfare events which are very cool and are simply that, what this mod aims for...
However afaik the modders of Deluge aren´t active anymore so it´s very hard to get in touch with them...
