perhaps, but 3 things should be taken into consideration 1) Galactus was growing in power as he was consuming the omniverse, so the list of cosmics who could pose a threat would be dwindling at a rapid rate; 2) Galactus had already consumed Celestials in order to get to that point and there's no reason to suppose that it wouldn't be a viable stratagem to apply to other, powerful obstacles and 3) the UN is a part of his being, so it may have been growing in power as a result of his overall rising levels of power.
anyway, on panel, nothing was stopping him but himself.
