Superman team what if

I get there are only so many things comics can do. Lately 2020 has gotten me down. MAYBE 2020 listened to dc too much and tried to get on board with this whole “year of the villain.” So my question is, what if the JL had enough? What if this time they get proactive. Would superman, wonderwoman, supergirl, shazam, and martian be enough to go and put darkseid into green lantern, and bring some peace to the rest of the universe?
