I agree with what you said ^ Also after seeing this past episode when Regina took control of Snow's body, I think Zelena posing as Marian would be more complex. Instead of a glamour spell, she probably took control of Marian's body (memories, feelings intact) so she could make sure she would be able to completely pose as Marian and keep up the charade.
