I have combined those two for years……very effective .

I can’t take ibuprofen but do combine acetaminophen and naproxen frequently. I would say 25% as effective as opioids.
I remember taking acetaminophen and aspirin for bad headaches many times. I think that’s what Excedrin Migraine is. Also used to take pain killers, aspirin and or Tylenol to prevent hangovers before going to bed after a night of binge drinking back in my college days in the 70s.
