Had another visit with the machinist today.

Came up with a much more practical approach that involves press fitting & welding a "stub shaft" in place of the internal splines currently pressed in the end of the motor shaft. This will essentially make the motor into a "normal" one with a short external shaft. Much easier to mate to the coupler.

He figured it will cost a couple hundred bucks, and will be ready late next week or early the week after.
