I have thought a fair amount about this.  The problem for really high
performance is that: as all the activity takes place around the stack pointer
it is difficult to get much pipelining in progress.  This means the cache
must be very fancy if you want to do Cray class machines, although RISC class
seems pretty easy.  I have toyed with this direction for a Ph.D. thesis.

(But then all that fancy compiler technique the RISC people cite would be
a waste :-)
(But the compiler induced bug rate would certainly go down.)
