This is another great theory amargo. What I envision is the name's wont mean anything as far as inside the manga (i.e. characters acknowledging the name contrast, etc) more it is just a foreshadowing tool for the readers. Also, I believe its gonna work in a manner in which Ichigo has a talk with zangetsu and he show's him how to use the all black getsuga tenshou to create a perfect darkness effect allowing him to fight without seeing aizen directly or something along those lines.
Thanks to the ass-wholeness of the ever illustrious Dick Fuld, I've been laid off. Thanks Lehman brothers!!!
