She probably doesn't, given that the issue's interview with Russell says that he was asked by the director on occasion to make Barbara sound more feminine. Plus, the way these two-handers work is that the companion plays whatever character they did on TV plus all of the "goodies". The guest actor then plays their main part, plus any incidental "baddies".

Having Small portray Barbara would almost certainly be confusing.

Anyway, Problem easily solved by just removing that line from Doctor Who Magazine/2012, which I've now done. Better to have reduced information than false information. Besides, that page is hardly the place for such info; best placed on The Revenants itself.
