I gave this some thought and here is what I came up with... not perfect, but do-able.
When I get the first set, I will have 1 officer and two different soldiers. When I get the second set I will have 2 officers and each leading 2 soldiers.
With the 3rd set, I will have 1 extra officer and 2 officers each with 3 soldiers. And with the 4th set, I will have 2 officers leading 4 soldiers plus 1 officer and by switching legs, I will use the extra officer minus the sword and belt, as an artilleryman.
Thus by switching legs and removing the extra swords I will have soldiers and artillerymen. It really will not work out even by switching red for white legs, but one unit of soldiers will have white legs and another will have red legs. Depending on how many of the French sets I get I could have two units each of the two soldiers plus cannon crews.
What do you think?
