I just started playing again after quite some time off and am playing Leipzig. I really can't stand the default look of the game, so I modded the 2D unit icons to have them look the way I want them to look. I started off with Philippe's mod as that was what was currently in my folder when I made the edits and then changed things from there.
Just backup your 2dSymbolsLg file in the maps folders and then drop this one into the maps folder and you should be good to go.
Please note that I did this for Leipzig, no idea if it would work for other games.
I freely admit to having "borrowed" the limber and supply wagon from Petersburg. The resolution is higher in those games, but it still works and I think looks cool. And what the heck, the Old Banshee folks have borrowed from me having used several of my figures in their ACW mod artwork (First Legion), so I'll borrow from them. ;-)
