7) Repeal 18 USC 922(0)
Great idea, but likely more than congress could handle in one fell swoop, so instead of outright repeal, I would suggest “deconstruction” of the law. This would mean first tearing it apart, neutering it, returning large chunks to state authority, and otherwise making it so it cannot be resurrected.
That is, not just putting a stake through its heart, but sewing garlic in its mouth, cutting off its head, and burying it at a crossroads.
