I am thinking of starting another space marine army (I already have Blood Angels, Dark Angels, Grey Knights and Black Legion). I want to start a new one to take advantage of the new book. I was originally going to go with Iron Hands but after reading the Badab Wars books I really like that Charcaradons. The thing I was thinking is the paint the army in Alpha legion colours using space marine kits. I could play them as whatever chapter I feel like, saying that the Alphas have poised as that chapter to incite uprising. I was wondering what other opinions are on my ideas.
