That's an interesting thought although since no zanpakuto, ever, has acted that way it does seem unlikely. Also that just sounds like a Shinigami-version Starrk 2.0

Also, in my eyes at least, Nozarashi has acted typical of a zanpakuto. It acts in a similar way to Yumichika's Ruri'iro Kujaku: a 'basic/partial' shikai release (when it becomes Fuji Kujaku) and a 'true/full' shikai release (when it becomes Ruri'iro Kujaku). Except in Zaraki's case it's constantly in its 'basic/partial' form until its release command is spoken.
