That'd be great. Except you also forgot that Hekapoo SIDES with the Solarias, even if she's not a fan of Mina. So the portals are all basically shut down. Hell, we had 2 episodes dedicated to this do you even watch the show?
Your better answer is to levitato YEET them the fuck off except.... oops, (1) Moon doesn't want to basically kill her own soldiers, (2) Mina still has self-propelled flying powers, so she's gonna come back anyways, (3) the only one who knows levitato (a Crescentia spell) is Moon because Star also has failed to properly learn it.
