I would happily buy Napoleonic artillerymen who are running for cover in a square or even defending their guns. Some wounded artillerymen and some in process of being cut down by cavalry would be some very unique poses.
Late war Napoleonic French foot artillery is a gaping hole in the genre. These should be done in a mix of firing and reloading poses, with some "bonus" figures like described above.
Napoleonic Prussian horse artillery is another much needed set.
