Ixa was going to be the main Rider. It's why they had all those CGI models that only showed up for one episode for his equipment. Past threads have said the Arm Monsters were actually going to be the enemy generals for the season before Imagine fever resulted in them becoming proxy Imagines, and Ixas fuestles would factor into defeating the monsters they summoned.
Once Den-O became massive they scraped everything but models and suits were already made, so the Kiva story we got was quickly thrown together, which is also why the suit was so fucking heavy, they didn't have enough time to test it properly.
