We discussed it, your mother and I. She has an extensive pro and con list of course, with 'but dueling Death Eaters is different than doing it for fun' as the big drawback. The rest... eh. People already want me dead and/or imprisoned. I don't see how an Order membership would make things worse in that aspect.
Of course, I might not be reliable at all times, given the whole on the run aspect, but other than that? Might not be a bad idea.
