I think it would only work with a Vichy France option to balance it out.
I have a soft spot for the Balance Mod’s rules, but the basic ideas remain the same.
French West Africa, Algeria, Tunisia, Morocco, French Central Africa, Madagascar, French Guiana, and French Indochina turn pro-Axis, as do all the units there.
The Balance Mod’s rules of having Southern France and its units (including the ships in sea zone 93) as pro-Axis but not allowing Axis troops to activate it work nicely.
I think your Free French rules would encourage more dynamic and individual conflict between the two French factions (as historically done). Maybe also have it so that Allied conquest of Vichy territories is always counted as liberating French ones (thereby giving it to the Free French)?
Would also add more incentive to Sealion (double capital capture!).
