I think it's pretty safe to say such a processor is unlikely to ever be
created, for the same reason there weren't any 48-bit computers when
32-bit computers ran out of steam: it caused more problems than it
solved, and Alpha pretty much proved that.  The engineering advantages
would have to be so overwhelmingly in favor for someone to want to walk
down that road again.
