I can understand the reluctance to go to 6 bit register specifiers, it
burns up your opcode space and makes encoding everything more difficult.
But today that is an unserviced market which will get customers to give you
a look. Put out some vapor ware and see what customers say.
If the issue is only the encoding, then presumably, Mitch could go the
route of a prefix instruction (like his PRED instruction or the
instruction he uses to do wide shifts/adds/...).
