Unlike the other visords, Ichigos inner hollow is his zanpakuto. So him using his soul reapers powers would already be a combination of that and hollow abilities plus the addition of his latent Quincy abilities. That's why when he uses getsuga with the smaller blade it is light in color (I think blue not sure) because that is his Quincy side channeling the attack and when using it with his bigger blade it is pure black because that is his inner hollow/zanpakuto spirit channeling it. So hollowfication for him is not possible as he has the rare case of naturally having a hollowfied zanpakuto.
