Goku vs. Galactus

If Goku can't beat Galactus to save his world. He would need the Spirit bomb to feed Galactus long enough for Galactus to spare earth, since he is now fed. what if The Living tribunal will have a role in a DBZ. (for anyone who don't know the Living Tribunal, he is the judge of keeping worlds balance. and his abilities are Nigh-omnipotence, Omniscience, Omnipresence)
