^Could be, yes. Everyone in Bleach having a somewhat unique core power/affinity that corresponds to their individual personalities or inner desires/fantasies or both (e.g. Orihime got op healing powers because she wished to be useful and powerful but still didn't want to harm anyone). But remember, Yhwach engraves a letter in the soul of every sternritter, that relates to their power, so he can either tell what sort of inner power they have and simply boosts it OR he gives them a power that matches their personalities.
