Using All Nighter vent tubes for secondary air?

[acp104]

Hi folks. I installed an old All Nighter Mid Moe sized stove over the weekend and I'm already thinking of what I can do to improve it. I think I'll add a baffle like in the attached picture, and I'm wondering if drilling the existing vent tubes that sit below the baffle in the picture would work for secondary air introduction. Air could be pulled from the vents on the stove top as well as from the back port where the blower is meant to be hooked up? A person could block off the rear port if that would work better. Any thoughts? Are the tubes way too large? Is adding secondary air a good idea in general?
