I'm just asking, why take that approach vs just building a Z80-based system to run CP/M?

OS-9 is a dramatically more capable OS than CP/M, in that it's a fully multitasking RTOS.

6809/6309 is an awesome processor. But Z80s and 6502s are still being made. And 20mhz range clock speeds. A 6809 or 6309 tops out at under 5mhz and you'll be getting your old chips off ebay, etc.
