I don't see an ISA switch being worth much. As I understand it today, most cores are basically an ISA interpreter on the front of a bespoke core. There's not much to be gained from using a specific ISA or arch (unless it's so different as to not be the same thing, like GPU vs CPU). Probably they could also go the way of making the guarantees provided by the processor as weak as possible, but that's even harder to switch to, I'd imagine.
