You are on to something here Ortwin.
I like the current mix of poses in Strelets cavalry sets and use them to make units with a mixture of poses, sometimes combining figures from a few sets to make a more or less ‘aggressive’ looking unit. The early carabiniers are a case in point and are in my top ten favourite sets.
What you are suggesting would make this easier to do and provide even more poses. Sounds great!
For sure - right that way. Belonging to what they actually are (waiting, travelling or whatever) with more baggage and even baggage organized differently on the saddle or beside their (lost?) horses doing this or that.
And i forgot to mention chinese & medieval russian and european cavalry like norman, carolingian and later one knights.
Maybe even india, samurai, scythian and gothic cavalry, (greeks including macedonian, persian including all the different dynasties as rome includes all troop-types from italic to sarmatian from republic to byzanthine).
