Yeah, I understand.
What could be done is some sort of hybrid, where the discrete CPU is used, and an FPGA is installed with some super simple dummy code so the accelerator works as if the FPGA weren't there. This would allow you to get the basics working, and then as you learn more about programming the thing, you can use it to emulate anything else that might be wanted, such as an MMU or FPU (and any related GLU logic).
Or at least design the circuit with an FPGA in mind (with any necessary stuff needed to get it working electrically) so somebody (if not you) can add it later without a major redesign.
