There was one anime that I watch that was an adaptation of a low-fantasy medieval novel written by a female author. The protagonist and her love interest were in a role reversal.

However, the rest of the setting follows traditional gender roles, although nobody seems to think it's particularly strange that the protagonist was a female warrior.
