no Renji's Hihio Zabimaru was an incomplete bankai because Zabimaru didn't trust him enough to allow him the full power so it capped the power it allowed him by giving him a false or half true name. However, Renji then met Ichibe Hyosube who decided that Renji was worthy of the true power and so revealed the true name as Soo Zabimaru thus allowing Renji full access to the full power. However, I believe that Renji may still be able to access the Hihio abilities.
