Manifesting a Zanpakuto Spirit requires years of training and specific concentration to do, like entering your own Spirits world!! It would not be productive during battle to suddenly concentrate on summoning your spirit, it would leave an opening and you would lose!! Also, the purpose of Zanpakuto spirits is individual growth, through interaction with them, it is a very personal matter since the spirit is an extension of the Shinigami using it!! The purpose of manifesting the Spirit in the real world is to prove yourself worthy of attaining Bankai and by whatever method, it forces a confrontation between you and the spirit!! So yeah not feasible for battle at all!!
