Or by someone who just so happens to look a fair bit like Malon! ;D

They don't really look all that much alike. Aside from similar age and hair color there are very few similarities, different dress style, height, bearing etc. But putting that aside horses are not stupid, various studies show that horses identify various members of their herd and differentiate their human handlers by a mixture of auditory and visual cues much like humans do. So unless Gaige also has an identical voice to Malon the horse still wouldn't recognize her. That and in the game Epona wouldn't come within five feet of Malon if she was with anyone else. She's a wild stallion.

You ever see that movie: Spirit - Stallion of the Cimarron? Epona's basically like that horse except she'll listen to a human if they play her song.

All of the other horses are broken though, they'll listen to anyone.
