Not to put the project down, but I would think long and hard about using spoilers for roll control in a KR. I have known of several aircraft that have employed them, and they had some unusual spin recovery techinques to say the least. Several pilots I know have flown twins with them, one specifically the Mitsubishi model, and had nothing good to say about the configuration. There are certain flight conditions where the spoilers just do not give enough roll control response, and I personally would only use them for speed control and altitude control, like the inboard mounted kind used for slowing down, or altitude loss.
