Well, I'm doubting Kubo planned THAT far ahead. I think Ichigo is talking more about the power to save and protect his friends, something he desperately wants. Think way back to the first chapter: without Rukia's power, he and his family would have died, and thus he wants power to "shatter fate", i.e. change the course of events. Although it would admittedly work nicely with the prophecy.
