In this case, it's better to imagine what could have than to see what it would have been. That's basically the 65816 documentation but 16 is find/replaced with 32. Some of time. A, X, and Y are 32-bit but the data bus is still 8-bit, address space is still 24-bit, stack, direct page, and program counter are still 16-bit.
