Emmental (Swiss) is NOT a high butterfat cheese. In fact, just the opposite. That is actually going to work against you by making a harder, inflexible rind. This greatly reduces your chances of getting any significant eyes.
For this one, I would just follow the brining instruction in RC's recipe and hope for the best.
You get an "A" for enthusiasm but I don't believe in jumping in with both feet until you have a good handle on the basics. Cheese tends to "sink" if you don't pay attention to detail and understand what's going on at every step along the way. Making a good cheese is not about blindly following a recipe. Give yourself a chance to learn by making lots of easier cheeses first.
