Well, with The Hogyoku's power, he cold gain full Shinigami abilities.

Reposted from http://bleach.wikia.com/wiki/Thread:86027 : The Hogyoku's true power is to the ability to sense the hearts of those around it and materialize their deepest desire. This ability gives it the power to break down the barriers between Hollows and Shinigami since THAT is what Aizen and Urahara desired it to do in their inventing it. As previously stated, Kaname Tosen, had hollow powers granted to him by Aizen with the Hogyoku as a reward for his service and loyalty. It can be assumed then that since it can grant a Shinigami full Hollow abilities that it can also grant full Shinigami abilities to Hollows. Now this brings into the question if that means the subject would have both a Shikai and a Bankai by default or if they would have to train like a normal Shinigami.

Also would they gain an Arrancar Zanpakuto as well or would their hollow abilities be sealed inside an Asauchi given to or taken by the Hollow? If the Hollow is already an Arrancar, would their false Zanpakuto be transformed into an Asauchi or would it be much like Ichigo and Kenpachi's own full time release Zanpakuto's? Or would they still require a REAL Asauchi to gain both Shikai and Bankai? Sadly there is little evidence based on the manga. The only thing we know can be observed again from Kaname Tosen, who possessed a real Zanpakuto which had Shikai, Bankai and Resurreccíon. his Zanpakuto took on the properties of both a normal Shinigami Zanpakuto and the ones that Arrancars have. However it's difficult to say whether or not an Arrancar's Zanpakuto would take on the properties of a Shinigami's. While it would have been nice to see Kubo's take on the subject it is likely we will never see the effect the Hogyoku on an Arrancar's Zanpakuto. This means the multiple hypotheses that could stem from this subject will never see any further evidence confirming or denying them.
