I was wondering if it would be possible to make a modification that focuses entirely on the hundred days campaign in Belgium. The map would be entirely of Belgium and Northern France and included the small villages and towns and chateaux that dotted the countryside - this could be based off one of the old boardgame maps for Napoleon's Last Battles or The Last Days of the Grande Armee. Instead of an abstraction like we get in the current Waterloo campaign the armies would be, as much as possible, 1:1 representations of the armies - and uniforms - of that specific campaign.
Factions would be:
French Imperial HQ and Garde (Napoleon)
French Left Wing (Ney)
French Right Wing (Grouchy)
British, KGL and Hanoverian (Wellington)
Dutch and Belgian (Orange)
Brunswick (Duke of Brunswick)
Nassau (Prince Bernard of Saxe-Weimar)
Prussian (Prince Blucher)
Russian (Prince Barclay de Tolly)
Austrian (Prince Schwartzenburg)
I was thinking that Generals would be (in part to cure the bad habit of Generals riding off like cavalry and getting killed) for the most part Dismounted foot types while ADC's would be small mounted units with limited Rally Capacity. In addition, there would be Band units - Imperial Guards and Highland Pipe Bands which function like generals with a rally capacity.
Alternatively... a scenario that would encompass only France and its borders in 1815 - ie. a grand strategic simulation of the 1815 campaign - would be fun too.
Just thinking out loud!
