Old School rules moved, aligned, fired and meleed each miniature individually. It's charming fun and perhaps bonds the player to each casting in some interesting way. It also detrimentally consumes an enormous amount of time. Some people have the time for this. Others don't.

Increase the size of infantry units to perhaps 48ish so they look more formidable than much smaller units. Yes, Lion in the Stars, using 15mms is an outstanding way to do this. Well said too.
Moving larger units changes the way we perform and think about wheels and passing by or through cover. It also allows less abstraction for formation changes. What I mean is, we don't say it takes a whole turn to form line to column. We actually march sub-groups into theses formations. We have an easy to read drill manual for this.
One example is close order cavalry backing up. Not at this scale – for us. Instead, the commander will do a right about or left about by 2s, 3s, 4s, troop, etc. No backing up like a truck with an alarm sounding beep, beep, beep. A cavalry player really needs to think and plan ahead. This item alone can be a tricky, fun and satisfying tactical problem. No shuffling (side-stepping cavalry either.
Here's another example with infantry:

Base individually and magnetize casting to underlying movement trays. We still keep artillery crews based and moved individually for the interesting visual effect.
Let's say 48 castings are placed on four underlying movement trays, each is moved plus aligned every turn and the game lasts seven turns. You have essentially 4x7 = 28 things to move.
By contrast a 48 man infantry unit moved individually without suffering losses will be handled 48x7 = 336 times. This is just one unit. Imagine if you did this for half a dozen.

Fire and melee by groups.
This is game of several brigades per side. How many? 2,3,4,5, and perhaps more if you ahve a lot of friends joining in with their own collections. It is not a grand tactical game of multiple corps.
---
As an aside I have collections with 16-20 casting battalions which fight grand tactically and where formation changes and maneuver is necessarily more abstract. I have no problem with this.
