You could have them go try to bust Todd and Black mask. Like half the gear has likely been trucked up and shipped off. You could try and stop them as they finish the shipments. It will be a difficult fight but not an unwinnable one.Drake needs to sell those alien guns and Emily can't be there when he sells them which leaves Cliff alone with the hyperactive lesbian that is crushing on her. So can do a job where get hired to fight some nameless thugs or Emily could drag Cliff around on a date.
Its fine i actually have a 5th hero in the works. Changed my mind about uncle sam. Im sure you will find this hero both familiar and surprising. But he is gonna be in gotham trying to take the shipment down. Perhaps he calls for help after a failed attempt to stop them.((Sadly. I really don't know))
