This can definitely work but it can also up the leaf to calx ratio by a lot in some strains. You really have to work with your fert-mix to keep N to a minimum when using CO2 from what I can tell. But yeah, you will grow more weight with the CO2 than without.
i dont think higher levels of c02 would increase just leaf production, ive been regularily upping c02 levels and notice more growth but not of just leaves.
