Hi, I'm Carys, one of the admins,
That's an interesting idea. It's not something we've ever thought of but in the aftermath of the war it would make sense for something like that to have happened. If you want to make such a connection yourself and add it into your sheet then feel free to do so. You can say it was arranged by the deputy headmaster, Samuel Dickinson, if you like (I play him so no worries about godmoding!)
BTW I noticed Gemma attended Beauxbatons for a year - so did my 6th year Hufflepuff, Linnet Willowsong (she was a Bellefeuille there), so if you'd like them to know each other I can PM you her sheet at some point? ...I should probably mention I don't actually play every character on the board...just that those two might help fit in with what you were suggesting xD
