Having made both the Brunello and Red MT. Cab several times each, the Red MT. Cab has a good bit more body than the Brunello, especially or because of the Cab's 2L grape pack. I doubt the Brunello will benefit even slightly from the amount of work you are planning on putting into it, Tony. It's your wine and you can do what you want, of course, but I think you will be disappointed that your efforts probably won't have as dramatic an effect on the Brunello kit as they would on a wine made from grapes or with a substantial Sangiovese grape pack.
I just don't think it has the body or 'frame' needed for the extra oak to be appreciable. I like an oaky wine, too, but I can't recognize the layering Mike is working toward, or the subtle differences in the toast levels of oak, so maybe that's just my tasting deficiency.
