In France? I might be confused, but I'm not understanding this part (unless you mean after the US marriage and AP) because K-1 marriages must take place inside the US. Once you marry anywhere (prior to K-1 marriage inside the US), the K-1 is void, and you have to start from scratch with a spousal visa.
We might have covered this earlier, but one option is to have a simple marriage now, and start the spousal visa process. You are then free to have celebration ceremonies any time and any place.
