Im not sure we want more French that are either inadequate or suffer from noticeable mistakes. After all the whole point in calling for more French is because we already have sets like that, which we want bettered.
I think French infantry for both pre 1812 and post 1812:
Marching: (in a battlefield formation)
In attack/advance: (like has been done for the British, Bavarians etc),
And in Firing lines
Covers most eventualities.
Yes variety is always good in sets, so long as its believable.
