I like Salubri's idea of Ichigo being a power mimic rather then any one thing. A unique power like that tracks well if you consider the Hogyoku granted Ichigo his wish ('I want to become more powerful'). The fact Orihime also expressed a unique power because of the Hogyoku lends support to it. So Ichigo is really not of any race and his parents' lineages also become irrelevant (except perhaps with gifting him an abnormally high spirit pressure).
