I have made the midwest kit(extract i presume) and it's nice man. Why up the ABV? I got a few "Big beers" in my rotation but the style calls for it. I have however (Imperialized) recipe's. That will drive your abv up, but sometimes the flavor profile goes to hell and you gotta use a very resilient yeast.
You gonna pull them pistols, or whistle dixie?
