I think Aizen made Tosen just that little bit more Hollow needed to use ALL of their powers. Ichigo will probably never be able to use resurrecion. However, for the Vizard, they may be able to reach that level, because when they were Hollowfied, it was still an EXPERIMENTAL FASE, meaning that the results could very well vary from the Hollowfication Ichigo has undergone.
