I'm betting not..
Even the SL3 bikes don't have anything about an "oversized BB shell" on the Specialized website. I'm 99% sure I can swap the GXP I just bought for the Powerspline BB, but I think I need to have a "GXP crank".
Question: Is the actual cavity needed for BB30 larger than that for GXP? I've seen adapters that allow a non BB30 crank in a BB30 compatible frame, but not vice versa, which leads me to to believe BB30 is bigger, and the adapters can only make things smaller.
