I know I saw this name here, but can't remember who it was. If it was you, or someone you know, I'd like to give credit where credit is due.
I've wanted to do a design like this for a while now with two body tube sizes and no transition. Originally I was working on a 4"-3" design, but downsized it to 3"-2.2". I wanted to be able to fly it on mid power G's at SARG, and small H's at Snow Ranch. I think I've succeeded. Open Rocket doesn't like the design, and keeps telling me there is discontinuity in body tube sizes. I had to do some trickery to get it to accept the fins on the lower section. I'm hoping that the stability and sims are relatively accurate. My gut feeling is stability won't be a problem, but the sims might be suspect.
