I don't know- In the screentime she got they only had her resisting about 38 kind of deaths. That's all. We don't know if she breathes, if she's got any blood to begin with, or even a digestive system - all we know is that statement in the movie about her pulling her power from Asgard, and being kinda invincible while Asgard stands. Was it allegory? One thing is sure, Hela resisted anything physical thrown her way, except for that huge Surtur attack while Asgard was being destroyed.
Maybe this have to do with Hela being goddess of death or something. Anyway, the Aquateam might have some hax here; I am not sure about the Queen's magical habilities, but they might be what's needed to deduce the "right" thing to do - Flood Asgard, in the destruction sense - then they would have a chance. It's the only way.
If it's by any other way, then Hela wins this 10/10, of course.
