her with mustache? i wonder how that would turn out to be if Ilda were to be drawn as grenadiers 
I might go with the Engineer or Artillery officers, given that they'd probably had more educational background and expertise, Napoleon himself was artillery officer before he rose to the ranks no?
Indeed, he started in the Royal Artillery.
The Austrian had a great artillery commander too, Josef Smola (seen in that painting I linked you before, and aslo here www.histoire-empire.org/persos…); You can turn Ilda's descendant into an artillery commander like him (common artillery gunner seems a bit below her family's status IMHO).
