They were also still some old design in services by the outbreak of the war. They were being phased out at the time:
Spad S510, last ones phased out of reserve squadrons in January 1940.
Dewoitine 371, mainly in French Navy. Gradually phased out until flight interdiction following several accidents in April 1940.
Of course, trademark of the late thirties FaF: Dewoitine 500&subsequent numbers.
Some were flying overseas until 1941!
Loire 46: one squadron used it until Fall of 1939.
Morane-Saulnier MS.225: some Twenty still in use in September 1939, scrapped by the May 1940.

Potez 540: few still served during Phony war, but were withdawn from Front line before German attack.

Farman F222: First allied bomber to attack Berlin.

And who would be courageous enough to play any campain in Amiot 143? Most were lost in May 1940, trying to stop german advance with almost-suicide attacks on bridges.
This would also be a great addition: LN 411, French navy dive bomber à la Stuka (used its landing gear as dive breaks).
And other French bombers too... LeO 451, Martin MB and so.
So if one wants to be quite complete, it will requires quite a lot of planes, even if MS406 were the most numerous ones.
I would love a start in septembre 1939, but perhaps april-may 1940 is more reasonnable.
By the way, it would be so sweet to fly this campaign.
It's a little known fact, but in one month and an half of fighting, the Luftwaffe lost as much planes as in BoB... Without Allied resistance in the air, later things could have been darker.
