I've refigured things since I posted about what my options were on the RSM Cavalry, and have realized that I actually don't need 1 bag of Hussars plus extras to make up 3 squadrons with the figures I have now. I had forgotten that the Old Glory command packs (which I'm not really fond of, but am using because it'd cost $40 or so to replace them) include an NCO with pistol, so if I used that figure as well as the officer/trumpeter/standard then I can make up 3 12-figure squadrons with just one more bag of the Hussars. 8 RSM Hussars plus the OG command pack per squadron.
I also have a single Sash & Saber NCO with pistol that was sent as a sample. I really love the sculpt, but I can't justify paying over $12 for a 4-figure set right now to replace the OGs. This will likely end up as an aide/guard for a command stand instead.
