I only recently ordered those books. (Age of X too oddly enough) I haven't read much of Dani's later day Valkyrie appearances.
Did you read any of the short-lived FEARLESS DEFENDERS comics?

It was canceled rather hastily but it featured Dani (in her Valkyrie role) and Misty Knight (badass private investigator) with other heroines in an Asgardian based story
I only found about it recently...
