10mm Black Powder

I have been busy with a few things lately.  One of which is the decision to purge my 28mm ACW collection.  The reasons for this are many, but it basically boils down to doing what makes me happy.  I originally thought I would just replace my 28's with 10's as that is the scale I want to use for Black Powder.  I purchased a few packs of Old Glory 10mm and painted up a few units.  One is a standard sized unit for Black Powder and the other would be a small sized unit.  These were a breeze to paint and look better from a distance which is the way it should be...10mm is for a massed look, and too much detail actually gets lost too close up.

My gaming friends are sticking with 28mm for Black Powder and are doing ACW and Napoleonics.  I don't want to duplicate their efforts initially, so I need to figure out a different period that I can do both sides for so they don't have to worry about it and I can be able to host games on my own.  I'm looking at the Crimean War, the American War of Independence, the Franco-Prussian War (and others during that timeframe), and the Sudan.  I'm not sure what I will end up doing...
