I know things have changed a lot since the PPC days, but it seems like this might not be the best idea, and that Apple's history might point this out.

I can see it for iOS devices, but for a legacy computer part of what's attractive to me about Macs is the base compatibility with commodity PC hardware. Of course, I also am not the hugest fan of the move toward merging iOS features into the desktop OS, so maybe I'm just being old fashioned about this.
