It would be rather hard though, as because of the shape there's a bigger effect caused by the force when firing the grenades, and it's harder to aim like that, and if firing while swinging horizontally the grenade may go flying somewhere far from the intended area.

Possible? Yes. But I think Nora's smart enough to know just how impractical doing that in Hammer mode would be, at least with her current skills.
