As for the overall issue, I'd lean towards what Hadrian's saying; the full power of the SS's should be unique to Quincy. The "energy blade" part...eh. I'm sure Vicente will research it, but I don't know if I could justify it being a heavy-duty threat to, if nothing else, other Arrancar. You'd think they'd be able to resist such things most of the time. *Shrugs*
