Street Fighter IV meets Rival Schools/Project Justice

This has been a wish of mine, to have Capcom include some members of Project Justice in the Street Fighter 4 Cast. Sakura is the only character in Street Fighter 4 from the Rival Schools game. Those who have played Project Justice on the Dreamcast & Arcade, which characters would you like to see included in Street Fighter. Given the dynamic difference in gameplay mechanics, would it be viable to integrate them into the Street Fighter 4 series. Voice your thoughts and opinions, and may our voices be heard. =)
