There was an actual possibility of that happening? I doubt that would happen but lets go with your worries for a minute here. They haven't revealed their names to anyone and the mothers are not actually known. We don't even know if their is a child of ravel and Issei's out there given from the spoilers. So going at it like that, it is possible that we will see some kids but not all. That would keep the "Risk" alive right?

Also to your explanation, about Gabriel and Serafall, I still can't see it, by that line of reasoning shouldn't Griselda be a possibility for him, or how about Jeanne. There is a possibility that they could interact with each other in the future and the girls could fall in love for him. I just haven't seen any evidence from the LN. I understand where you are coming from but it just doesn't seem likely to me.
