I would have more fun to see dismounted unit like medieval.
For example: equites are wealty or noble citizens who fight as legionary cavalry, but i read that often they dismount in battle and fight as heavy infantry.
In ancient battle (to 3rd century AD) cavalry has secondary rule in battle and horsemen are outnumbered in all army.
Many soldiers, use horses for come quickly behind enemy... after that they dismount for charge enemy from back.
Would be good thing to see in PI many dismounted units
Can PI team thinking about this?
