The merc companies are badly outdated with the new system in place, since even Mongol Mercenaries cap out at 6 cavalry, while most regular mercs cap out at 2 or 4, if they have any at all. Maybe that could be updated in the future?

Arumba has this video where he explains why cav are bad and what would make them good: https://youtube.com/watch?v=h-62B7GiwDw

He suggests that cav should move further to the middle of the combat line, depending on the width of the (remaining) enemy combat line. That would improve combat really really by a lot IMO. Perhaps you could integrate this idea in this mod. I don't know if it is hardcoded, however.

The deployment of regiments on the battleline is entirely hardcoded AFAIK. a bandaid solution however is to increase the base flanking range of cavalry, it is 2 as base in vanilla, then multiplied by modifiers from tech or flanking range ideas.
