That's a good question. Idk. Seems as if it might, although it'd probably be rare but if that's the case, it could happen. Just have to try it.
I'd try and get it to work taking the french stuff first and then adjust as needed.
But yea, you could have a trigger that changes ownership once France falls. That's kinda how the Vichy rule works now, so I'd think your idea would work.
