What about Hudson Lieck (Calisto in Xena) for Cpt Kat Muller from New Frontier.
I don't see it. Muller's kind of a statuesque woman, isn't she? The 6-foot-tall Marjorie Monaghan has been suggested for her (though she's also been suggested for Domenica Corsi). Leick is a respectable 5'8", but quite skinny; I never found her physically convincing as the ultrapowerful warrior she was shown to be on Xena
, though her superb acting compensated for that.
