I think the "microprogramming" bit can/should simply be a multi-cycle, non-pipelined implementation.
Non-pipelined is easier to write and debug, especially if you are used to regular sequential programming; once you have that working then it isn't too hard to turn it into a pipelined implementation.
A basic RISC style design is probably easier than a Z-80 because of the simpler addressing modes and the simpler decode.
