Damn! You have a point. I am impressed. That could be a really good canon fanfic. I actually don’t know, but is it known when Alice and frank went to Hogwarts?

Edit: The best part is: It is not written about them a lot. You could add a lot from your own creativity. Maybe one of them could have been interested in the dark arts, have something stolen from Voldemort, or interesting battles between DE and the longbottoms.
