Your ideas are what I had in mind originally. A mix of types of personnel. Add in some medical personnel, bandsmen, unusual combat poses (GC's clubbing pose) and who knows what else. The need for many different types of personnel is why I suggested that Strelets go back to its original set structure of 50 or so poses even if it increases the price of the set.
For Napoleonics, Strelets could start with an updated French Napoleon's General Staff (Set 1)with some added features such as medical personnel and deleting Napoleon and the senior staff to make room. By updated, make the set to today's quality standards.
