Would it be possible (as it was in MTW) to have mounted units dismount before a battle? Say if the terrain was unsuitable for cavalry ops, or during a siege. You wouldn't have to create any new units necessarily- just find a close analog in existing units- horse archers becoming foot archer for instance. Not only would it be realistic (and cool), it would also give you more strategic flexibility.
I bet someone's gonna tell me it can't be done.
