For explaining the lithium's disappearance, maybe, but we do need something to explain the relative proportions.
My default assumption was as a light element Li would be one of the top numbers. If, say (and these numbers are way off), you were expecting the universe to be 50% hydrogen, 25% helium, 12% lithium, 13% other, and you only had 4% lithium, then that missing 8% would have to be reflected somewhere, and you'd be seeing 54% hydrogen in the universe, for instance.
Except as I look it up, lithium is very rare to begin with, so maybe two thirds of a very small number isn't enough to throw off the calculations for the other elements. In reality it's 74% hydrogen, 24% helium, and less than 2% for everything else. Li is some exceptionally tiny fraction of a percent, so even if it is off, that's not going to shift the relative percentages of other elements enough to be noticeable, I don't think.
