My guess is because he needed the others to operate the Kindenju properly.
Prior to the team's discovery of the jewels, he had to control Ryuseioh with his own ki, which was apparently quite taxing on him. Without the others, Dairenou would never have been controllable (never mind the fact that he didn't have the jewels to summon the other four Kidenju in the first place, nor the ability to control them individually), which would make a huge difference. We're talking about the main robo, which was used in nearly every battle since it's debut. Even it wasn't enough now and then, there's no way he'd get by with Ryuseioh alone.
As to why he didn't just fill one of the suits himself, I dunno. It was never really explained how or why Shouji and Kazu were recruited, maybe he simply ended up with an extra guy and figured, "why not?"
