IMHO, the only way I would have a problem with it is if Alice in some way tried to brag about how a blind girl could best a sighted, able-bodied man in a duel. So long as Alice doesn't try to make it seem like Skyndarbau is a clumsy oaf who can't handle a sword ("Oh look how pathetic he is, that a blind little girl bested him with a sword. How pitiful". etc., etc.) If both sides play it as the absurdly unlikely outcome that it turned out to be, then I don't see any big deal with it.
Same.
Also, I would like to briefly express my appreciation for the complex that game BM really is. I think it's amazing these kind of issues come up on a regular basis.
