There's no assuming if she can or not, she's shown to only handle Keith (the weakest 9 demon gate) who she gave it her all to and even BEFORE she knew what'll happen once she defeats him, she kind of was having a hard time with him. And don't matter, she managed to handle 3 and it would've stayed that way if Torafuza kept on fighting Loke and wasn't immune to Aquarius' water which is how Jackal and Lamy gained the advantage. And once again, I know he wasn't in his Etherious form which is why I only compared her to Base Natsu who couldn't defeat Base Jackal.
