Brooks said it was ugly that some instructions (RX) had both base and
index registers while others (SS) only had base registers, which I
expect made it even harder to do what you suggested.

Depending on base registers for both data and branches was one
of the ideas that did not age well, I think.  We have since
seen in the RISC machines that having a stack implemented via
a register, with possibly a frame pointer, a global offset and
larger offsets (16 bits) works well, and we know how to generate
position-independent code.

This is, of course, with 20/20 hindsight.
