I see almost no outcome that Trump overturns this without an actual Civil War, and no one not in the Trump family would go that far. No recount has ever swung a state more than what, 2000 votes? No judge is going to invalidate hundreds of thousands of votes, which is what the Trump campaign is demanding in PA. It would take multiple state legislations to flip their electors in order to ensure a Trump win. There just aren't enough Trump rumpswabs to pull all of this off.
There's an old legal adage that seems apropos here. "When you have the facts, pound the facts. When you have the law, pound the law. When you have neither the facts nor the law, pound the table."
What we're seeing now is a child pounding the table. No more, no less.
