I agree with everyone on this one. Sportsmaster and Cheshire will have obviously seen Artemis work with other weapons besides a bow and arrow, but you have to remember it's been a long, long time since she's done that. There is still some 'Artemis' style in the way she moves in a fight as Tigress, but it'll be hard for even her father and sister to guess who she is. Not to mention, as you said, Tupka, that they obvious think she's dead. So yeah, the only plausible ways they could find out is either they put a bow in her hands, she tells them the truth or the glamor charm is broken or just randomly stops working.
