I've thought that would be the best result for her for a while now. She's portrayed as a potential savour for common people but her ambition to be queen is rooted in her mad Dad's bloodline, her pack of fire breathing monsters, her army of formerly enslaved eunuchs and her mad brother's obsession. She's never even seen Westeros afaik. If she went to Westeros, it'd be as a foreign conqueror not a liberator.
Plus it's too obvious. Everytime she looks like she's in trouble, something bails her out. Her becoming queen would be a bit of an anti climax imo. I'm hoping her current storyline doesn't result in her just becoming Queen of all Dothraki because dragons (or something).
