Well, they might start off as rivals. The protectors could see the brawlers as a threat to the peace they are trying to maintain. Maybe there would be some initial skirmishes or misunderstandings between them.
In the fanfiction, they might initially be a bit wary of each other due to their different backgrounds. The Weasleys, being a wizarding family, and the Grangers, muggles who are very academic.
