Yeah, I've done it. It's tough, but kind of simple; you just kind of grind away at the boss's health while looking out for moves that could actually hit you. you basically want to always be in scythe mode since it lets you spam the slide which will go through most of her moves (aside from the uppercut, which you'll have to dodge/perfect guard). While she's staggered you can go into gun mode and use the shotgun for damage. One thing that can definitely help: you can use items during the fight.
