The crows were a damn mess last season and need a new leader to step in and knock some sense into their heads. I would argue that Mariah would be able to herald them to victory and dominance in Jon Snow's wake.
She has already established that she can don the garb perfectly and look like a goddess at the same time.
Not only that but she has been shown to be an excellent leader in battle, as seen in the epic Game of War ads.
She also has established the perfect theme soundtrack to her eventual domination in
Hero,
Almost Home, and
Triumphant
Yes I know the crows can only consist of men but they've broken so many damn rules already I think she would find away around it. I think she would be able to lead not only the crows but eventually take the crown as true queen of Westeros through her shady and spirited ways.
What say you ATRL? Is Mariah the savior GoT is in need of?
