Before there is a Dictator, there is a Leader. A good Leader knows his
boundaries and avoids stepping into the "Dark Side". :)

I agree with you here. Even developing big graphics games on the CoCo3,
the 64K barrier is a problem. A big speed increase can be had if one
didn't have to shuffle 8K MMU blocks around just to access 512K or more.
I'm sure it would help with OS-9 too in a big way.
So maybe a FPGA CoCo should also have a custom 6809/6309 core with a
32bit address line?
