Sure, as long as Hermione is Accio-ing it within a reasonable range/in line with her canon abilities to summon the wand, I'll give you one undead to stabbity like that.
it's technically Lily Evans accio-ing it, in this situation. if not sufficient and hermione were to try with someone else's wand i think it would probably not do any undead damage on the way due to it being someone else's wand.
