I like the rivalry although some facts about Sora aren't correct. Anti-Sora is just the darkness in Sora's heart that sometimes can take over, it's not really a clone of him. However Sora's Heartless appears as a boss in coded (but he isn't very important). Maybe you could take Roxas because he was one of the bad guys.

Birth By Sleep wasn't a spin-off it was a very important game to the series but it takes 10 years place before the original so Sora couldn't fight back then since he wasn't given the power of the keyblade yet.

Riku wasn't possessed by Ansem, he only took the appearance of Ansem and hid from Sora because he didn't want him to see him like that. Riku was manipulated by Maleficent to turn to the evil side but luckily turned normal again later.

And to Battlelord, Sephiroth is from Final Fantasy.
